Add values to a matrix from a loop

Hi,
I have the following lines in my script:
for j=0:15;
percentage_change = (x((8+j),k)-baseline1)/baseline1*100;
end
The above gives me 16 different values. Could anyone please tell me how I would go about putting all these 16 values in an empty 16x1 matrix called P? Thank you so much for your help.

This should help!
P = [];
for j = 1:15
percentage_change = (x((8+j),k)-baseline1/baseline1*100;
P = [P, percentage_change,];
end

P = percentage_change;
Of course after you do that P is no longer empty.

Since I can't run your code. I really recommend you take the same actions I would take to solve your issues. And that is to carry out the actions you will learn in this video: http://blogs.mathworks.com/videos/2012/07/03/debugging-in-matlab/

P = zeros(16,1);
for j=0:15;
percentage_change = (x((8+j),k)-baseline1)/baseline1*100;
P(j+1) = percentage_change;
end
Sorry for not indenting code, I don't know how to do that...

@Nathanael Ferster, glad it helped. Maybe it's a little known trick. If more people would type control-a then control-i in MATLAB before pasting in here, then it would sure make the code easier to follow. Of course after they paste it in, they still need to highlight it and click the Code icon to format it as code and enable the "copy" button so that people can copy the entire code with one click.
