I am given a table with 2 columns - one contains P_in, the other P_out:
P_in = table(:,1)
P_out = table(:,2)
I want MATLAB to find the corresponding values of P_out to a set of P_in. I.e. I have P_in2 which is a subset of P_in. I want MATLAB to return the corresponding output values. I tried:
P_in2 = find(table(P_in2,2));
I get an error: Subscript indices must either be real positive integers or logicals.
So apparently find() can only deal with integers. Also, I think, find() only returns indices. How can I solve this problem?

Hi Luki,
You could try using the functions "arrayfun" and "find" together to resolve the issue.
The relevant indices can be found using the following command:
>>idxs = arrayfun(@(x)find(P_in==x,1),P_in2)
Now you can use these indices to index into P_out as follows:
>>ans = P_out(idxs);
Hope this helps!
