CoppMatrixF64 Struct Reference

Library-owned column-major f64 matrix returned to C. More...

#include <core.h>

Data Fields
double *	data
	Pointer to the first column-major element, or null for an empty matrix.
size_t	rows
	Number of matrix rows.
size_t	cols
	Number of matrix columns.
size_t	capacity
	Allocation capacity in number of double elements, used only by copp_matrix_f64_free.

Detailed Description

Library-owned column-major f64 matrix returned to C.

C callers may read data[0..rows * cols] using column-major indexing and must release the matrix exactly once with copp_matrix_f64_free.

Example

The example below reads a column-major path-evaluation matrix and releases all returned matrices.

struct CoppMatrixF64 q = {0};
struct CoppMatrixF64 dq = {0};
struct CoppMatrixF64 ddq = {0};
check(copp_path_evaluate_up_to_2nd(path, s_slice, &q, &dq, &ddq));
 
double q_row_i_col_j = q.data[i + j * q.rows];
copp_matrix_f64_free(ddq);
copp_matrix_f64_free(dq);
copp_matrix_f64_free(q);
