4.4.2 MatrixMultiply

Description

MatrixMultiply performs the matrix multiplication between the source one and source two matrices and places the result in the destination matrix.

Symbolically:

where:

0 ≤ i < numRows1

0 ≤ j < numCols2

0 ≤ k < numCols1Rows2

Prototype

fractional* MatrixMultiply (int numRows1, int numCols1Rows2, int numCols2, fractional* dstM, fractional* srcM1, fractional* srcM2);

Arguments


Parameters	Description
numRows1	Number of rows in the source one matrix.
numCols1Rows2	Number of columns in the source one matrix which is same as number of rows in the source two matrix.
numCols2	Number of columns in the source two matrix.
dstM	Pointer to the destination matrix
srcM1	Pointer to the source one matrix
srcM2	Pointer to the source two matrix

Returns

Pointer to the base address of the destination matrix.

Remarks

If the absolute value of result in dstM[r][c] is larger than the maximum value of the 1.31 fractional data type, this operation results in saturation for the (r,c)^th element.

If the source one matrix is squared, then this function can be computed in place and can be self-applicable.
