From: Jose on 28 Jun 2010 12:50 Hello guys, i am interested to write down a variable with strings + numbers... a=[2 3 4] channela(1)=1;....i.e channel1 channela(2)=2;...i.e channel2 channela(3)=3;...i.echannel3 How can convert a(1) in string...i suppose is with the command num2str, but how it works to get channel1? Thanks,

From: Jose on 28 Jun 2010 13:29 Sorry us, but it does not work with eval and sprintf when iI have this kind of variable proc1m...i am interested to supply 1 for a(x), where a=[2 3 4]... something like that: sprintf('proc%dm', a(1))); does not work... Any help? proc1m=uicontrol('parent',hfigure{i},'String', num2str(panel(i)),... 'Position', [240,400,60,20]); "Jose " <jose.l.vega(a)gmail.com> wrote in message <i0ajsp$6t5$1(a)fred.mathworks.com>... > Hello guys, i am interested to write down a variable with strings + numbers... > > a=[2 3 4] > > channela(1)=1;....i.e channel1 > > channela(2)=2;...i.e channel2 > > channela(3)=3;...i.echannel3 > > How can convert a(1) in string...i suppose is with the command num2str, but how it > works to get channel1? > > Thanks,
