binary_ops.h

Operations between two matrices.

Functions

sfloat slap_NormedDifference(Matrix A, Matrix B)

Return the normed difference between 2 matrices of the same size.

Returns \( \sqrt{\sum_{i=0}^{m-1} \sum_{j=0}^{n-1} (A_{ij} - B_{ij})^2 } \)

Parameters:

Returns:

NAN if input is invalid, normed difference otherwise

enum slap_ErrorCode slap_MatrixAddition(Matrix C, Matrix A, Matrix B, sfloat alpha)

Add two matrices, with scaling.

Calculates \(C = A + \alpha B\)

Matrices must all be the same size.

Any of the matrices can be aliased.

Examples

Normal matrix addition

slap_MatrixAddition(C, A, B, 1.0);

Subtract a matrix from another, in-place

slap_MatrixAddition(A, A, B, -1);

Parameters:
