Compresses the memory footprint occupied by a matrix.
Remark: The compression is required when you handle a large matrix onto which several calculations have been made. If this matrix contains several null columns and/or rows, the compression is used to significantly reduce the memory footprint of matrix.
Example
// Compress a matrix
MatStack("MyMatrix")
Syntax
MatStack(<Matrix>)
<Matrix>: Character string
Name of matrix to compress, defined by MatCreate.
Remarks

Existence of matrix to compress

The matrix existence is not checked. To check the matrix existence, use MatExist.

Managing errors

Caution: MatStack returns no result. To find out whether errors have been generated by the compression, use MatError on this matrix. To get more details on the error, use ErrorInfo with the errMessage constant.
