There are 920,000/3 = 306,666 elements for temporary matrices when performing matrix manipulations. The default is to use 3,000 rows and 100 columns. The largest square matrix is about 550x550.
The MATRIX DIMENSION allows you to modify the rows and columns for the temporary matrices. The number of rows cannot be set greater than the maximum number of rows for a variable (set to 20,000 on the default implementation).
Since this command only dimensions temporary matrices during the computations, you can enter this command as often as you wish during a single Dataplot session.
where <ncols> is a number or parameter that specifies the maximum number of columns for the temporary matrices.
where <nrows> is a number or parameter that specifies the maximum number of rows for the temorary matrices.
