MATLAB: Beginner MATLAB question (I just started using matlab a week ago)

beginnerfindMATLAB

Please help give the function to solve this. Thank you

Simpler and more efficient to use logical indexing:

idx = ss(:,1)==1;
out = ss(idx,2)

If you really want to use |find|:

idy = find(ss==1);
out = ss(idy,2)

Basic MATLAB concepts, such as how to use indexing, are explained in the introductory tutorials:

you have to do an eval.

eval(['Fish2_', num2str(i), ' = Data(1,3,i);'])

instead of

Fish2_i = Data(1,3,i);

You need to call the function with all of its output arguments, e.g. (pick the names to suit your needs):

[A,B,C,D] = DiagDom();

Very basic MATLAB concepts, e.g. how to call functions with multiple output arguments, are explained in the introductory tutorials:
