Parallelism-in-Matrix-ComputationsThis repository contains 5 sections of programs to solve various matrix computation problems. The following is based on the MPI/OpenMP programming paradigm, and was tested on four nodes of the MC cluster.1. Implement BBTSBlock banded triangular solver to solve Lx = b, where L is a banded lower triangular matrix with m subdiagonals.2. Implement a SPIKE-like algorithmSolve Lˆy = f, where Lˆ is a banded lower triangular matrix of order N = 32, 768 = 215, with t = 128 subdiagonals on a cluster of multicore nodes.The SPIKE-like algorithm should be implemented using MPI. In this algorithm, use BBTS (from Part (a)) to solve the system involvings Lˆi.3. Block LU Factorization with boostingSolve the dense linear system Ax = b using the approximate block LU Factorization algorithm with the procedure of ”diagonal boosting”Let α be a multiple of the unit roundoff, e.g. 10−6, and aj be the jth column of the updated matrix A after step j − 1. In step j, if the diagonal pivot does not satisfy |pivot| > α||aj ||1, its value is ”boosted” as, pivot = pivot + β||aj ||1, if pivot > 0, pivot = pivot − β||aj ||1, if pivot 4. The Spike algorithmImplement the Spike algorithm in Chapter 5.2.1 to solve Ax = b, where A is a banded matrix, on a cluster of multicore nodes.5.

1 to the fundamental polymer mode at port 2 which is given by |S21|^2 with port 1 at the input side, and port 2 at the output. However, since the device behaves symmetrically, we can get the same result by looking at |S12|^2. For more information about the S-matrix index mapping see EME solver analysis.Analysis and ResultsPressing the run button will calculate the modes at each cell. You can visualize the calculated modes by expanding the EME solver and cell group in the Objects Tree, then right-clicking the individual cell and selecting the result to visualize.To see the final field profile of the device as well as the S-matrix results, press the EME PROPAGATE button in the EME analysis window. Once the propagation is complete, profile monitor results and S-matrix results will be available, and can be visualized by right-clicking on the objects in the Objects Tree. The results for different propagation lengths can also be changed without having to re-calculate any modes. The field profile for a tapered region of length 10 um and 100 um are shown below.10 um taper (xz plot)100 um taper (xz plot)Scattering parameters relate the transmission and reflection coefficients for each port and input/output modes of the device. This is automatically calculated by the EME solver, and returned as the result of an EME solver region. The internal s-matrix includes all of the s-parameters for all the modes of all the ports, whereas the user s-matrix will contain only the s-parameters for the modes selected in the ports. Since we have 2 ports, and we are only interested in the fundamental mode at each port, the user s-matrix will be a 2 by 2 matrix, with elements S11, S12, S21 and S22.Length scanningThe propagation sweep widget allows you to scan the length of any cell group and calculate s-matrix results automatically. The S-matrix index mapping table allows you to quickly identify which s-matrix components correspond to which port and mode.Below, the transmission through the taper is plotted over taper lengths from 10 um to 200 um.The length scanning can also be done by running the script spot_size_converter.lsf.EME vs 3D FDTDWe also compare the EME results with 3D FDTD. The results between two solvers agree reasonably well, however they are done with completely different time scale. The EME simulation takes 3 minutes to simulate 101 different taper lengths (blue squares), whereas 3D FDTD takes 6. java matrix data-structures matrix-calculations matrix-manuplation matrix-data linear-system-solver matrix-math-library matrix-determinant-calculation.

A world space; \(P^i\) is a projection matrix for camera \(i\), \(x_j^i\) is 2D coordinates of a keypoint in image \(i\) that corresponds to the 3D point \(\mathbf{\hat{X}_j}\) and \(P^i \mathbf{\hat{X}_j}\) is a backprojection of point \(\mathbf{\hat{X}_j}\) to image \(i\).I need to mention that this is a simpler formulation than usually encountered in full SLAM problems because we are not optimizing camera projection matrix \(P^i\) here (It’s known in the Apolloscape dataset). Furthermore, there is also no weighted matrix that accounts for variances in error contributions between different world points.Below, we continue the reconstruction of our three image examples with the resulting merged map of ten 3D points that correspond to 46 equations in the Bundle Adjustment Optimization problem. Bundle Adjustment Optimization for three image pairs.Without camera poses computation, as in a full SLAM problem, we set only 3D map points as parameters to the Ceres solver, which performs Non-linear Least Squares optimization using the Levenberg-Marquardt method.Ceres solver was optimized to work with huge problems, so the optimizations of 1.4M 3D points is not too large for the library to handle (though it is demanding for CPU computation on my MacBook Pro:)In order to save computation time, I run a Bundle Adjustment Optimization with Ceres solver only after I merge 40k new 3D points to the global map. Such a sparse optimization approach works because the problem is a constraint in just 3D map-point optimization with known camera poses, and thus is more or less localized in the parameter space. When calling solve.Before solve can call a solver, the problems must be converted to solver form, either by solve or some other associated functions or objects. This conversion entails, for example, linear constraints having a matrix representation rather than an optimization variable expression.The first step in the algorithm occurs as you place optimization expressions into the problem. An OptimizationProblem object has an internal list of the variables used in its expressions. Each variable has a linear index in the expression, and a size. Therefore, the problem variables have an implied matrix form. The prob2struct function performs the conversion from problem form to solver form. For an example, see Convert Problem to Structure.For nonlinear optimization problems, solve uses automatic differentiation to compute the gradients of the objective function and nonlinear constraint functions. These derivatives apply when the objective and constraint functions are composed of Supported Operations for Optimization Variables and Expressions. When automatic differentiation does not apply, solvers estimate derivatives using finite differences. For details of automatic differentiation, see Automatic Differentiation Background. You can control how solve uses automatic differentiation with the ObjectiveDerivative name-value argument.For the algorithm that intlinprog uses to solve MILP problems, see Legacy intlinprog Algorithm. For the algorithms that linprog uses to solve linear programming problems, see Linear Programming Algorithms. For the algorithms that quadprog uses to solve quadratic programming problems, see Quadratic Programming Algorithms. For linear or nonlinear least-squares solver algorithms, see Least-Squares (Model Fitting) Algorithms. For nonlinear solver algorithms, see Unconstrained Nonlinear Optimization Algorithms and Constrained Nonlinear Optimization Algorithms. For Global Optimization Toolbox solver algorithms, see Global Optimization Toolbox documentation.For nonlinear equation solving, solve internally represents each equation as the difference between the left and right sides. Then solve attempts to minimize the sum of squares of the equation components. For the algorithms for solving nonlinear systems of equations, see Equation Solving Algorithms. When the problem also has bounds, solve calls lsqnonlin to minimize the sum of squares of equation components. See Least-Squares (Model Fitting) Algorithms.Automatic DifferentiationAutomatic differentiation (AD) applies to the solve and prob2struct functions under the following conditions:The objective and constraint functions are supported, as described in Supported Operations for Optimization Variables and Expressions. They do not require use of the fcn2optimexpr function.The solver called by solve is fmincon, fminunc, fsolve, or lsqnonlin.For optimization problems, the 'ObjectiveDerivative' and 'ConstraintDerivative' name-value pair arguments for solve or prob2struct are set to 'auto' (default), 'auto-forward', or 'auto-reverse'.For
