Matrix parameters are entered by extending the Array syntax: Simply place a vertical bar (|) character between rows, for example:


...Xmatrix=[1.2 .3 .3 | .3 1.2 3 | .3 .3 1.2] ! (3x3 matrix)


Symmetrical matrices like this example may also be entered in lower triangle form to be more compact.


...Xmatrix=[ 1.2 | .3 1.2 | .3 .3 1.2 ] ! (3x3 matrix lower triangle)
