.Modelica_LinearSystems2.Utilities.Streams.readMatrixB2

Information

Syntax

B = Streams.readMatrixB2(fileName, matrixName, nx, nu);

Description

Opens the given MATLAB MAT file and returns the submatrix B of the matrix matrixName given as

B[nx, nu] = matrixName[1:nx, nx+1:nx+nu];

Example

// Generate dslin.mat of the double pendulum example first
Modelica_LinearSystems2.Utilities.Import.linearize(
  "Modelica_LinearSystems2.Utilities.Plants.DoublePendulum", 1.0);

// Read B matrix of the linearized system
readMatrixB2("dslin.mat", "ABCD", 6, 1)
//  = 
// [0.0;
//  0.13297862810901506;
//  0.0;
// -0.022602364424528787;
//  0.0;
// -0.11931966525935421]
