1.4.20 vsip_dmgetcolstride_p - Get Column Stride of a Matrix View

vsip_stride vsip_mgetcolstride_f(const vsip_mview_f *v); 
vsip_stride vsip_cmgetcolstride_f(const vsip_cmview_f *v);

Description

This function returns the column stride of a matrix view, which represents the number of elements to skip in memory when moving from one column to the next within a row.

Parameters

• const vsip_dmview_p* v: Pointer to the matrix view.

Return Value

• Returns the column stride as a vsip_stride value.

Example

vsip_mview_f *matrix; 
vsip_stride col_stride; 
 
// Create a standard row-major matrix 
matrix = vsip_mcreate_f(100, 100, VSIP_ROW, VSIP_MEM_NONE); 
col_stride = vsip_mgetcolstride_f(matrix); 
printf("Standard matrix column stride: %ld\n", col_stride);  // Typically 1

Notes

• For row-major matrices, the column stride is typically 1 (contiguous elements along rows).

• For column-major matrices, the column stride equals the number of rows.

• For transposed views, the column stride of the transposed view equals the row stride of the original matrix.
