mlfCov (MATLAB C Math Library)

Covariance matrix

Minimum input arguments: one, maximum: user-defined. Terminate the list of arguments with a NULL.

C Prototype

mxArray *mlfCov(mxArray *x, ...)

C Syntax

#include "matlab.h"

mxArray *x;            /* Required input argument(s) */
mxArray *Y, *Z;        /* Optional input argument(s) */
mxArray *C = NULL;     /* Return value */

mlfAssign(&C, mlfCov(x,NULL));
mlfAssign(&C, mlfCov(x,Y,NULL));
mlfAssign(&C, mlfCov(x,Y,Z,NULL));

MATLAB Syntax

C = cov(X)
C = cov(x,y)
