Turning a list of answers into a single array

9 views (last 30 days)
I would like to know how I can(if I can) put my answers into a single matrix/array... for example: ans=12 ans=13 and=73 ans=59 and so on, and would like it in the form [12;13;73;59]

How does ans get its successive values?

I was given a file(y) with a matrix in it, with ID numbers in the 1st column and a bunch of random numbers on the right. I had to enter a users ID and receive all the random numbers that were on the same row as the ID numbers.
for x=1:size(y)
results=y(x,2);
if(ID==y(x,1));
disp(results)
end

If you want to capture the output of some operation, then you need to accept it into some variable. If you don't and just let it spew out "ans = ...." to the command window then you can't put those into a variable unless you used diary() and then parsed the file - a major pain.

Regarding your loop you just added, to get the second column of y into results, do this:
results = y(:, 2);
Now, to print out results where the first column of y equals some ID number:
rowsToPrint = y(:, 1) == ID; % Logical index
fprintf('%f\n', results(rowsToPrint));
Note: no for loop is needed at all.

Example
a=zeros(1,10);
for k=1:10
a(k)=sin(k);
end
