How to vary matrix of matrices in a loop?

In my program i have got the value of

RpMats{k} = Rp;

Where RpMats is an array of matrices and each element of RpMats is 50x50 matrix. Example: RpMats = [(50x50 matrix) (50x50 matrix) (50x50 matrix) (50x50 matrix) .... (50x50 matrix)] I have total 100 matrices in RpMats. I want to use these elements of RpMats (which are matrix) in the below loop:

for j = 1 : 50
X = max( Rp(j,:)-RecPackets, 0) ; 
end

% here Rp is the input of first element of RpMats, then second element of RpMats like this. Which means by mentioning Rp i want to provide input from the RpMats. first input of Rp will be the first matrix of RpMats Like this i want to give all the 100 matrix of RpMats as input to Rp. Is it possible?

Basically you need two indices. One to specify which matrix of your array you want to adress, lets call that index jj. And further the index which adresses the element of each matrix, e.g. ii.

Then you can create (for example) a nested loop:

for jj=1:number of matrices in array
    for ii=1:50
        Rp{jj}(ii,:) = do something
    end
end

So cell arrays (what your matrix array is) are adressed with {...} returning a matrix of doubles and this matrix is then adressed with (...).

If you want to use something like Rp{jj,:} - I'd recommend {Rp{jj,:}} (for example when you have a matrix of matrices but you're just interested in a certain column, you could filter it like that.
