Dividing all matrix elements

To divide all matrix elements by a given value, multiply the matrix by: 1/<Value>.

Matrix existence

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

Managing errors

Caution: MatFloatMultiply returns no error code. To find out whether errors have been generated by the multiplication, use MatError. To get more details on the error, use ErrorInfo with the errMessage constant.
