- Multiplying matrices
- Existence of the result matrix
In french: MatMultiplie
// Multiply two matrices
ResMultiply = MatMultiply("Matrix1", "Matrix2", "MyResultMatrix")
<Result> = MatMultiply(<1st matrix> , <2nd matrix> , <Result matrix>)
- True if the multiplication was performed,
- False otherwise. To get more details on the error, use ErrorInfo with the errMessage constant.
<1st matrix>: Character string
Name of first matrix to multiply, defined by MatCreate.
<2nd matrix>: Character string
Name of second matrix to multiply, defined by MatCreate.
<Result matrix>: Character string
Name of the matrix that contains the result of the multiplication. This matrix is automatically created when the two matrices are multiplied.
To multiply two matrices, the number of columns in the first matrix must be equal to the number of rows in the second matrix.
The element (row I, column j) of the result matrix is obtained by multiplying the row I of the first matrix by the column j of the second matrix.
A matrix can be multiplied by itself. To do so, use the same matrix name for <1st matrix> and <2nd matrix>.
Existence of the result matrix
The matrix existence is not checked. This matrix is overwritten if it existed beforehand. To check the matrix existence, use MatExist
