WINDEV      WEBDEV    WINDEV Mobile      Others MatFloatMultiply (Function)
In french: MatRéelMultiplie
Multiplies each matrix element by a value. This multiplication is performed in the specified matrix.
// Multiply the matrix elements by 3
MatFloatMultiply("MyMatrix", 3)
Syntax
MatFloatMultiply(<Matrix Name> , <Value>)
<Matrix Name>: Character string (with quotes)
Name of the matrix to use, defined by 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>.

Existence of matrix

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 find out the error details, use ErrorInfo associated with the errMessage constant.
