vand

Perform logical AND operations on real-number vectors.

The function interface declaration is as follows:

Operations on numbers of the bool type:

void (vsip_vand_bl)(const vsip_vview_bl *a, const vsip_vview_bl *b, const vsip_vview_bl *r);

Parameters

Parameter

Description

Value Range

Input/Output

a

Pointer to the source vector

The value cannot be NULL.

Input

b

Pointer to the source vector

The value cannot be NULL.

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

    int32_t dst[BUFFER_SIZE_T];
    int64_t stride = 1;
    uint64_t offset = 0;

        printf("%d ", dst[i]);
    }
    printf("\n");
}

int main(void) {

Output:

src1:
1 6 -1 0 3 -4 0 9 -5 2
src2:
-1 0 4 -18 13 0 0 -3 5 0
dst:
1 0 1 0 1 0 0 1 1 0
