I am wanting to save the table data that is being written each loop, instead the data is being overwritten. I was going to try to do: info = [info output] that didn't work and I can't do info(i,:) = output because those deminsions do not line up. And the "table" varible I am not sure what I could do there to store all the data as oppsed to looping over it each time.
Thank you

Your info needs to be initialized outside the loop, right?

Gotcha, when I try that i get "Dimensions of arrays being concatenated are not consistent.
" due to the fact that each iteration the deminsions change.

Resolved it, got everything in a cell then did vertcat with said cells.

You need to use indexing to assign the results of each loop to a new location. Look at this example on the for loop documentation page.
You may also want to consider going though Ch 13 of MATLAB Onramp.

Share the code (copy/paste. No one wants to transcribe from a screenshot) along with the complete error message (all the red text).

Sorry about that, I actually just got it using cells however then I had to figure out how concatinate vectors of different number of rows. Vertcat came handy there.
Thank for all the help
