Vector array

void amd_vrda_sub(int len, const double *lhs, const double *rhs, double *dst)#

Computes elementwise difference for double arrays.

Parameters:
  • len – Number of elements.

  • lhs – Left-hand array.

  • rhs – Right-hand array.

  • dst – Output array of differences.

void amd_vrsa_subf(int len, const float *lhs, const float *rhs, float *dst)#

Computes elementwise difference for float arrays.

Parameters:
  • len – Number of elements.

  • lhs – Left-hand array.

  • rhs – Right-hand array.

  • dst – Output array of differences.

Indexed Arithmetic

void amd_vrda_subi(int len, const double *lhs, int inc_a, const double *rhs, int inc_b, double *dst, int inc_res)#
