 def acscd(i1): return o0  (1)
 function o0 = archr_core_acscd(i1)  (1)

Description

Computes the Inverse Cosecant in Degrees:

• to the range defined by:

• [i1_first, i1_last)
• [i1, i1 + sz)

and stores the result in another range, beginning at o0.

• of its i1ument and returns it.

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/acscd.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_acscd_f32(o1, i1, sz);
for (i = 0; i < sz; ++i) {
printf("%4lu: acscd(%f) = %f\n", i, (double)i1[i], (double)o1[i]);
}
}
