Hello,
I have a large 3D array Q (17019x68x50).
I'd like to create a new 2D matrix modeQ which is 68×50 (i.e. the latter two dimesions), with the values being the modes of each corresponding column in the array.
I'm interested only in non-zero modes, but other values are much less frequent than zero, so mode(Q,1) throws out a matrix of only zeroes.
I do not understand the nonzeros function enough to utilise it correctly either.
