Description

Class for accessing the Matlab engine with a C++ wrapper.

When a ChMatlabEngine object is instanced, a Matlab engine is started (assuming Matlab is properly installed and its dll are available on the system) and following funcitons can be used to copy variables from/to Chrono, and to execute commands in Matlab. Useful also to exploit the powerful plotting features of Matlab. Note! to compile programs that include this header, your makefile must be properly configured to set the Matlab SDK directory, so that matlab headers and libs can be compiled/linked Also, if you run an executable that used this header on a system that has no Matlab installed, a 'missing dll' error will pop up as soon as you try to start the program.

#include <ChMatlabEngine.h>

◆ GetVariable()

bool chrono::ChMatlabEngine::GetVariable	(	ChMatrixDynamic< double > &	mmatr,
		std::string	varname
	)

Fetch a matrix from Matlab environment, specifying its name as variable.

The used matrix must be of ChMatrixDynamic<double> type because it might undergo resizing.

◆ PutSparseMatrix()

bool chrono::ChMatlabEngine::PutSparseMatrix	(	const ChSparseMatrix &	mmatr,
		std::string	varname
	)

Put a sparse matrix in Matlab environment, specifying its name as variable.

If a variable with the same name already exist, it is overwritten.

◆ PutVariable()

bool chrono::ChMatlabEngine::PutVariable	(	ChMatrixConstRef	mmatr,
		std::string	varname
	)

Put a matrix in Matlab environment, specifying its name as variable.
