How can I create a bigger matrix/array, having 200 zeros matrices in it?

I want to compute HSV histograms for 200 images, and for this purpose I have to initialize 200 zeros matrices for computing and saving the values in each zeros matrix. How can I do that in MATLAB? Thanks

Presuming you fix the number of bins for each, just

h=zeros(200,nBins);  % should do it

If you're going to use different sizes, you'd either use cell or perhaps nan instead of zeros to have the indicator missing value in an array.

I'd wonder if you couldn't, however, write the processing to not need all 200 of them in memory at the same time.

Kindly tell: what exactly am I suppose to pass in "nBins"? I have 3 channels for each of the 200 images(H,S,V),

It's the number of bins you're wanting...in this case I gather that would be 3.
