1.4.22 vsip_dmgetrowstride_p - Get Row Stride of a Matrix View

vsip_stride vsip_mgetrowstride_f(const vsip_mview_f *v); 
vsip_stride vsip_cmgetrowstride_f(const vsip_cmview_f *v);

Description

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

Parameters

const vsip_dmview_p* v: Pointer to the matrix view.

Return Value

Returns the row stride as a vsip_stride value.

Example

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

Notes

For column-major matrices, the row stride is typically 1 (contiguous elements along columns).
For row-major matrices, the row stride equals the number of columns.
For transposed views, the row stride of the transposed view equals the column stride of the original matrix.
