Hello,
I have an array
nN = 6; N = 1:nN;
I want to make a legend where nN changes and so may not be known ahead of time. I found the following solution on another post, but it doesn't work for me.
legendCell = cellstr(num2str(dope, 'N=%-d'));legend(legendCell)
I get the error.
Error using legend>process_inputs (line 563)Cell array argument must be a cell array of character vectors.Error in legend>make_legend (line 328)[autoupdate,orient,location,position,children,listen,strings,propargs]= process_inputs(ha,argin); %#ok
Error in legend (line 282) make_legend(ha,args(arg:end),version);
So, I tried
for iN = 1:nN legendCell{iN} = cellstr(['n = ' num2str(N(iN))]); end legend(legendCell)
which gives a similar error. However, the following does work.
legendCell = {'n=1', 'n=2', 'n=3', 'n=4', 'n=5', 'n=6'}; legend(legendCell)
Why does the later work but the others don't?
