                                                double threshold)

Cuts the given matrix at the specified threshold and returns a binary matrix containing the same number of values as the input one. Any value in the input matrix greater than or equal to the threshold will transform to a one in the output matrix. Other values in the input matrix are transformed to a zero in the output matrix.

Parameters:

toCut - not null, may be incomplete.
