Description

Computes the sec:

Parameters

i1_first, i1_last

The range of input elements

o0

The beginning of the destination range, may be equal to i1

i1

The scalar/contiguous data input element

Example


#include <time.h>
#include <stdio.h>
#include <stdlib.h>
#include <stdint.h>
#include <stddef.h>
#include <archr/core/sec.h>

double rand_in(double min, double max) {
  return min + ((double)(max - min) * ((double)rand() / RAND_MAX));
}

int main() {
  time_t t;
  size_t i;
  size_t sz = 10;
  float* i1 = (float*)malloc(sz * sizeof(float));
  float* o1 = (float*)malloc(sz * sizeof(float));

  srand((unsigned int)time(&t));
  for (i = 0; i < sz; ++i) {
    i1[i] = (float)rand_in((float)-10, (float)10);
  }
  archr_core_sec_f32(o1, i1, sz);
  for (i = 0; i < sz; ++i) {
    printf("%4lu: sec(%f) = %f\n", i, (double)i1[i], (double)o1[i]);
  }
}
