FUNCTIONcalcCovarMatrix

RETURN TYPEvoid

Call structure. A void return can still write to destination arguments. The parameter descriptions define inputs, outputs and ownership.

Note: use #COVAR_ROWS or #COVAR_COLS flag

calcCovarMatrix(samples: Mat, covar: Mat, mean: Mat, flags: number, ctype: number): void;

2 available overloads

calcCovarMatrix(samples: Mat, covar: Mat, mean: Mat, flags: number): void;

calcCovarMatrix(samples: Mat, covar: Mat, mean: Mat, flags: number, ctype: number): void;

samples: samples stored as rows/columns of a single matrix.
covar: Output destination, filled by the native operation. output covariance matrix of the type ctype and square size.
mean: Input/output value, modified by the native operation. input or output (depending on the flags) array as the average value of the input vectors.
flags: operation flags as a combination of #CovarFlags
ctype: type of the matrixl; it equals 'CV_64F' by default.
