vsip_dmcopy_p - Copy Matrix Views

Core

This manual is preliminary and incomplete.
While our Core implementation implements all functions given in the standard we are still working on completing this documentation.

Please refer to the VSIPL standard for a complete function reference of the Core profile until we have completed work on this documentation.

4.1.2 vsip_dmcopy_p - Copy Matrix Views

void vsip_mcopy_f_f(const vsip_mview_f* A, const vsip_mview_f* B); 
void vsip_cmcopy_f_f(const vsip_cmview_f* A, const vsip_cmview_f* B);

Description

These functions copy the contents of one matrix view to another, with optional type conversion. The functions handle both real and complex matrices of various precision levels:

vsip_mcopy_f_f: Copy from float matrix to float matrix
vsip_cmcopy_f_f: Copy from complex float matrix to complex float matrix

Parameters

const vsip_dmview_p* A: Pointer to the source matrix view
const vsip_dmview_p* B: Pointer to the destination matrix view

Example

vsip_mview_f *src_matrix_f; 
vsip_mview_f *dst_matrix_f; 
 
// Copy float matrix to float matrix 
vsip_mcopy_f_f(src_matrix_f, dst_matrix_f);

Notes

The source and destination matrices must have the same dimensions.
For type conversion functions, appropriate rounding or truncation is applied when converting to integer types.
When converting from higher precision to lower precision (e.g., double to float), values may be truncated or rounded.
The matrices can be views of larger matrices or blocks, allowing for copying of submatrices.
