In french: MatRéelMultiplie
Multiplies each matrix element by a value. This multiplication is performed in the specified matrix.
Example
// Multiply the matrix elements by 3
MatFloatMultiply("MyMatrix", 3)
Syntax
MatFloatMultiply(<Matrix> , <Value>)
<Matrix>: Character string
Name of the matrix to be used, defined with MatCreate.
<Value>: Real
Value used for the multiplication.
Remarks

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.
