Saving data for each iteration in a for loop

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?

[nathan stallworth]

the data that needs to be I believe is outside of the loop.

[Yongjian Feng]

I meant your info variable needs to be outside the loop. Something like thsi

info = [];
for i=1:9
    info = [info output];
end

[nathan stallworth]

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.

Yes I usally do that but since the values changes deminsions that indexing approach makes it a slightly trickier. Could possibly use cell arrays?

[Cris LaPierre]

Cell arrays or structures could work.

You could also consider appending the new table to the existing one.

I am attempting the cell route running itno not supported varibles of this type. They are just doubles, not sure what types cells support am going to find out.

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
