- *
- * Multiplies a matrix by a scalar. This is accomplished by multiplying each element in the
- * matrix by the scalar. For example:
- * \image html MatrixScale.gif "Matrix Scaling of a 3 x 3 matrix"
- *
- * The function checks to make sure that the input and output matrices are of the same size.
- *
- * In the fixed-point Q15 and Q31 functions, <code>scale</code> is represented by
- * a fractional multiplication <code>scaleFract</code> and an arithmetic shift <code>shift</code>.
- * The shift allows the gain of the scaling operation to exceed 1.0.
- * The overall scale factor applied to the fixed-point data is
- * <pre>
- * scale = scaleFract * 2^shift.
- * </pre>
