X= [some matrix I already stored and I want to add guassian noise to it, and average them out]
X_23= X + randn(size(X));
X_24= X + randn(size(X));
X_25= X + randn(size(X));
X_26= X + randn(size(X));
X_27= X + randn(size(X));
X_28= X + randn(size(X));
X_29= X + randn(size(X));
X_30= X + randn(size(X));
.
.
.
and so on

In a word, DON’T!
Do this instead:
N = 42; % Choose A Number
for k1 = 1:N
Xn(k1,:,:) = X + randn(size(X));
end
It will then be much easier to do operations on your ‘Xn’ (‘X noise’) matrix.
