Loop over cell content possible?

ChristianKehrer

Dear script experts,

 

Do you know, if there is a way (e.g. by using cells) to write strings into a kind of 'matrix' to use in a for loop afterwards. The idea behind is to make many different plots, which are always stored under different names and then have different titles.

Maybe, someone has already done something similar?

 

Thank you in advance!

Hi Christian,

 

maybe this 8 lines of code can help you:

 

clc,clear,close all
plotnames = cell(4,4);
for ii=1:size(plotnames,1)
    for jj=1:size(plotnames,2)
        plotnames(ii,jj) = ['plot, row ',num2str(ii),' & column ',num2str(jj)];
    end
end
plotnames

 

Cheers,

 

Lorenzo

Thanks for this Skript.

One more Question. Now we have a kind of cell Matrix.

 

Is it possible to use this cell Matrix for labeling my Axis in a plot.

I thougt this should work, but the solver Needs a 'real' String.

 

f=plot(x,y);

xlabel(Plotnames(1,1));

ylabel(Plotnames(1,2));

 

Would be great if someone worked with this Problem bevore.

Thanks

Ludwig

Hi Ludwig,

You can convert the cell into a struct using cell2struct, but I think it is too cumbersome.

An easier way is to use directly a struct with the limitation of having only one dimension, but named fields. The script looks lke this:

 clc,clear,close all  for i = 1 : 4     plotnames(i).title = ['plot, title ',num2str(i)];     plotnames(i).xlabel = ['xlabel ',num2str(i)];     plotnames(i).ylabel = ['ylabel ',num2str(i)]; end  % direct access or within a loop title(plotnames(3).title); xlabel(plotnames(3).xlabel); ylabel(plotnames(3).ylabel);

Hi Ludwig,

 

I believe that the solution suggested by Ronald it's great.

 

Anyway, this should fix the error you were experiencing:

 

xlabel(Plotnames{1,1});

ylabel(Plotnames{1,2});

 

I have just replaced () with {}.

 

Cheers,

Thanks for this help, the path you two showed me is verry efficient.
