Q3Matrix3x3_Multiply

You can use the Q3Matrix3x3_Multiply function to multiply two 3-by-3 matrices.

TQ3Matrix3x3 *Q3Matrix3x3_Multiply (
const TQ3Matrix3x3 *matrixA, 
const TQ3Matrix3x3 *matrixB, 
TQ3Matrix3x3 *result);

matrixA

A 3-by-3 matrix.

matrixB

A 3-by-3 matrix.

result

On exit, the product of matrixA and matrixB.

DESCRIPTION

The Q3Matrix3x3_Multiply function returns, as its function result and in the result parameter, the product of the two 3-by-3 matrices matrixA and matrixB.
