MATLAB: Sum all the Channels in matrix

MATLABmatrix operiationmerge the channelssummationwithout loops.

Hello everyone,

Let say I have a matrix M of 100 x 100 x 5. How can I sum all the channels of M and get one matrix R of size 100 x 100 only. I want to do it without loops.

Best Answer

R = sum(M,3);

I am a little confused, do you mean like this:

Y = reshape(1:18,6,3)  % A manageable dimension.
Y_1 = sum(Y,2)

So in your case it would be

Y_1 = sum(Y,2).';

Or do you mean, more like this:

Y = 1:18
Y_1 = sum(reshape(Y,3,6))

So in your case it would be

Y_1 = sum(reshape(Y,320,467))

x = rand(100); 
n0    = sum(x(:) == 0);
n0to1 = sum(x(:) > 0 & x(:) <= 1);
ngt1  = sum(x(:) > 1);
