RETURN TYPEnumber

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

Returns the determinant of a square floating-point matrix.

The function cv::determinant calculates and returns the determinant of the specified matrix. For small matrices ( mtx.cols=mtx.rows<=3 ), the direct method is used. For larger matrices, the function uses LU factorization with partial pivoting.

For symmetric positively-determined matrices, it is also possible to use eigen decomposition to calculate the determinant.

determinant(mtx: Mat): number;

mtx

input matrix that must have CV_32FC1 or CV_64FC1 type and square size.

Returns

The number result.
