change of variable
显示 更早的评论
I asked this question before but I missed an important point:
I would like to be able to Change 'X7' . I don't want to Do anything with the "X" because I have Y7, Z7,K7 in other plots. Basically I just want to be able to change the digit "7" and not the letters.
Here is my code:
subplot(3,2,1)
Hs=spectrum.periodogram;
psdest = psd(Hs,X7,'Fs',Fs);
semilogx(psdest.Frequencies,10*log10(psdest.Data));
grid on;
xlabel('Frequency (Hz)')
ylabel('dB/Hz')
title('X7')

Please use code formatting as explained in the "MArkup help" link on this page.
The question is not clear. Do you want to change the name of the variable? Perhaps this helps: http://matlab.wikia.com/wiki/FAQ#How_can_I_create_variables_A1.2C_A2.2C....2CA10_in_a_loop.3F

If you read the answers to your previous same question, both answers provide valid solution.

Perhaps the answer being looked for here is a variation of Fangjun's earlier answer.
N = 7;
Str = sprintf('X%d', N);
psdest = psd(Hs,eval(Str),'Fs',Fs);
title(Str);
