C Specification

#include <nitro/fx/fx_mtx22.h>

s32 MTX_Inverse22(const MtxFx22 * pSrc, MtxFx22 * pDst);
    

Description

If an inverse matrix exists, this function stores the inverse matrix that is located in *pSrc in *pDst, and then returns 0. If no inverse matrix exists, a non-zero value is returned, and *pDst will be unchanged.

pSrc and pDst can be pointers to the same matrix.

Arguments

pSrc The pointer to a 2x2 matrix.
pDst The pointer to a 2x2 matrix.
