Starting from the NumPy official documentation, the behavior of the function is the following:

numpy.any(a, axis=None, out=None, keepdims=novalue)

Test whether any array element along a given axis evaluates to True.

Also, in that case, you gave to this function just the array, so in Python the function is called with some default parameters, so axis= None, out=None and keepdims=novalue. Just the first one is interesting for you, so:

The default (axis = None) is to perform a logical OR over all the dimensions of the input array

So I suppose that if just one element of the array is positive, this function return true, you have just to check each element of the array/Mat

Also, in that case, you gave give to this thie function just the input array, so in Python the function is called with some default parameters, so parameters: axis= None, out=None and keepdims=novalue. Just the first one is interesting for you, so:

So I suppose that if just one element of the array is positive, this function return true, true: you have just to check each element of the array/Mat

The default (axis = None) is to perform a logical OR over all the dimensions of the input array

So I suppose that if just one element of the array is positive, this function return true: you have just to check each element of the array/Matarray/Mat to find if at least one element is positive, so it return true, otherwise false.
