void	plp_mat_fill_I_stride_f32_parallel(uint32_t N, uint32_t stride, uint32_t nPE, float *restrict pDst) Glue code for creating a strided 32-bit floats identity matrix in parallel.

Functions Documentation

function plp_mat_fill_I_stride_f32_parallel

void plp_mat_fill_I_stride_f32_parallel(
    uint32_t N,
    uint32_t stride,
    uint32_t nPE,
    float *__restrict__ pDst
)

Glue code for creating a strided 32-bit floats identity matrix in parallel.

Parameters:

• N Width and height of the matrix
• stride Stride of the matrix (elements between each row)
• nPE Number of cores to use for computation
• pDst Points to the output matrix

Return: none
