void vsip_ccorr1d_getattr_f(const vsip_ccorr1d_f *cor, vsip_ccorr1d_attr_f *attr);

Description

This function retrieves the attributes of a 1D correlation object and stores them in the provided attribute structure.

Parameters

• const vsip_dcorr1d_p* cor: Pointer to the 1D correlation object created with vsip_dcorr1d_create_p .

• vsip_dcorr1d_attr_p* attr: Pointer to the attribute structure where the correlation object attributes will be stored.

Example

vsip_corr1d_f *corr; 
vsip_corr1d_attr_f attr; 
vsip_length m = 1024;  // Input signal length 
vsip_length n = 64;    // Reference signal length 
 
// Create correlation object 
corr = vsip_corr1d_create_f(m, n, VSIP_SUPPORT_FULL, 100, VSIP_ALG_TIME); 
if (corr == NULL) { 
    fprintf(stderr, "Error: Could not create correlation object\n"); 
    return; 
} 
 
// Get the attributes of the correlation object 
vsip_corr1d_getattr_f(corr, &attr); 
 
printf("1D Correlation Object Attributes:\n"); 
printf("  Ref length: %lu\n", attr.ref_len); 
printf("  Data length: %lu\n", attr.data_len); 
printf("  Support region: %d\n", attr.support); 
printf("  Lag length: %lu\n", attr.lag_len); 
 
// Clean up 
vsip_corr1d_destroy_f(corr);
