4.9.2 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.
