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.

1.4.25 vsip_dmputoffset_p - Set Matrix View Offset

vsip_mview_f* vsip_mputoffset_f(const vsip_mview_f *v, vsip_offset off); 
vsip_cmview_f* vsip_cmputoffset_f(const vsip_cmview_f *v, vsip_offset off);

Description

This function modifies the offset of an existing matrix view. The offset determines where the matrix view begins within its associated data block, measured in elements from the start of the block.

Parameters

const vsip_dmview_p* v: Pointer to the matrix view to be modified.
vsip_offset off: The new offset in elements from the start of the block.

Return Value

Returns a pointer to the modified matrix view.

Notes

The new offset must be such that the entire view fits within the block boundaries.
The condition for a valid offset is:
$offset+ row_length× row_stride+col_length ×col_stride <block_size$
