How can I make the following into a loop?

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.
