4.5.2 vsip_vand_p - Boolean Vector Logical AND

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

Description

This function performs a logical AND operation between corresponding elements of two boolean vectors $a$ and $b$ , storing the result in the output vector $r$ . The operation performs element-wise logical AND:

ri= ai∧bi

for all $i$ from 0 to $n-1$ , where $n$ is the length of the vectors.

Parameters

const vsip_vview_p* a: First input boolean vector.
const vsip_vview_p* b: Second input boolean vector.
const vsip_vview_p* r: Output boolean vector that will store the result.

Example

vsip_vview_bl *a, *b, *r; 
vsip_length n = 10; 
 
// Create boolean vectors 
a = vsip_vcreate_bl(n, VSIP_MEM_NONE); 
b = vsip_vcreate_bl(n, VSIP_MEM_NONE); 
r = vsip_vcreate_bl(n, VSIP_MEM_NONE); 
 
// Initialize vectors with some boolean values 
// For example, set alternating true/false patterns 
for (vsip_length i = 0; i < n; i++) { 
    vsip_vput_bl(a, i, (i % 2) == 0);  // true for even indices 
    vsip_vput_bl(b, i, (i % 3) == 0);  // true for indices divisible by 3 
} 
 
// Perform logical AND operation 
vsip_vand_bl(a, b, r); 
 
// The result vector r will now contain true only where both 
// a and b had true values (indices 0, 6) 
 
// Clean up 
vsip_valldestroy_bl(a); 
vsip_valldestroy_bl(b); 
vsip_valldestroy_bl(r);
