Information
This information is part of the Modelica Standard Library maintained by the Modelica Association.
Example model that shows how to read a Real matrix in MATLAB MAT format from file using functions readMatrixSize and readRealMatrix.
Additionally, specific matrices from the supported file formats are loaded and it is checked whether the loaded matrices have the expected values.
