void vsip_conv1d_getattr_f(const vsip_conv1d_f *conv1d, vsip_conv1d_attr_f *attr);

Description

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

Parameters

• const vsip_dconv1d_p* conv1d: Pointer to the 1D convolution object created with vsip_dconv1d_create_p .

• vsip_dconv1d_attr_p* attr: Pointer to the attribute structure where the convolution object attributes will be stored.

Example

vsip_conv1d_f *conv; 
vsip_conv1d_attr_f attr; 
vsip_vview_f *h; 
vsip_length h_len = 31;  // Impulse response length 
vsip_length n = 1024;    // Input signal length 
 
// Create impulse response vector 
h = vsip_vcreate_f(h_len, VSIP_MEM_NONE); 
 
// Create convolution object 
conv = vsip_conv1d_create_f(h, VSIP_SYM_NONE, n, 1, 
                           VSIP_SUPPORT_FULL, 100, VSIP_ALG_TIME); 
if (conv == NULL) { 
    fprintf(stderr, "Error: Could not create convolution object\n"); 
    return; 
} 
 
// Get the attributes of the convolution object 
vsip_conv1d_getattr_f(conv, &attr); 
 
// Clean up 
vsip_conv1d_destroy_f(conv); 
vsip_valldestroy_f(h);
