max - function in opencv that can give the minimum value of a 2d or 3d matrix along a specific dimension -

-

is there function in opencv, can compute minimum value of 2d or 3d matrix along specific dimension. , give me index of minimum value.

minimizing in 1 dimension mean, if have 3d matrix result should 2d matrix, , if have 2d matrix result should 1d matrix(array) of indices min/max value stored.

minmaxidx , minmaxloc gives global minimum index/value along dimensions.

cv::reduce give row or column wise minimum or maximum. don't think give index. "find()" function lacks in opencv.
