Functions

Name
int plp_mat_inv_f32(float restrict pSrc, float restrict pDst, uint32_t N)
Glue code for matrix inversion of 32-bit floating-point matrices.

Functions Documentation

function plp_mat_inv_f32

int plp_mat_inv_f32(
    float *__restrict__ pSrc,
    float *__restrict__ pDst,
    uint32_t N
)

Glue code for matrix inversion of 32-bit floating-point matrices.

Parameters:

  • pSrc Points to the input matrix. pSrc is modified by this function
  • N Width and height of both matrices
  • pDst Points to the output matrix

Return: 0: Success, 1: Matrix is singular, 2: operation not supported

Par: This function will use plp_mat_inv_i32s_xpulpv2 for its computation.

Glue code for matrix inverse of a 32-bit floating-point matrices.
