vfill

Perform filling operations on real-number vectors.

The function interface declaration is as follows:

Operations on numbers of the float type:

void (vsip_vfill_f)(float alpha, const vsip_vview_f *r);

Parameters

Parameter

Description

Value Range

Input/Output

alpha

Real-number scalar

Unlimited

Input

r

Pointer to the destination vector

The value cannot be NULL.

Output

Abnormal Input

When a null pointer is input, the function directly returns a result.

Example

#include <stdio.h>
#include <stdlib.h>
#include <stdint.h>
#include "kvsip.h"
#include "vsip.h"
#include "vsip_type.h"

#define BUFFER_SIZE_T 10
void VfillExample()
{
    float alpha = 1.32f;
    float dst[BUFFER_SIZE_T];
    int64_t stride = 1;
    uint64_t offset = 0;

    vsip_block_f *block_r = vsip_blockbind_f(dst, BUFFER_SIZE_T, VSIP_MEM_NONE);
    vsip_vview_f *r = vsip_vbind_f(block_r, offset, stride, BUFFER_SIZE_T);
    vsip_blockadmit_f(block_r, VSIP_TRUE);

    vsip_vfill_f(alpha, r);

    vsip_valldestroy_f(r);

    printf("alpha: %.2f\n", alpha);
    printf("dst:\n");
    for (int32_t i = 0; i < BUFFER_SIZE_T; ++i) {
        printf("%.2f ", dst[i]);
    }
    printf("\n");
}

int main(void) {
    VfillExample();
    return 0;
}

Output:

alpha: 1.32
dst:
1.32 1.32 1.32 1.32 1.32 1.32 1.32 1.32 1.32 1.32
