vsip_dmgetblock_p - Get the Data Block from a Matrix View

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.

1.4.15 vsip_dmgetblock_p - Get the Data Block from a Matrix View

vsip_block_f* vsip_mgetblock_f(const vsip_mview_f *v); 
vsip_cblock_f* vsip_cmgetblock_f(const vsip_cmview_f *v);

Description

This function returns a pointer to the data block associated with a matrix view. The data block contains the actual storage for the matrix elements.

Parameters

const vsip_dmview_p* v: Pointer to the matrix view.

Return Value

Returns a pointer to the vsip_dblock_p associated with the matrix view.

Notes

Multiple matrix views can share the same data block.
The block should not be destroyed directly if it’s still being used by any matrix views.
This function is useful for:
- Creating additional views of the same data with different parameters
- Checking if two matrices share the same underlying storage
- Performing operations that require access to the raw data
