Hi Guys,
I have some variables (D1,D2,D3,...) and I want to draw the graph for them .Since, number of variables are so much, I want to define the plot funtion in such a way that the variable changes automatically. My initial suggestion was to use eval function as follows: plot(eval(['D' num2str(j)])(:,11),D11(:,1),'linewidth',1) But id doesnt work. Could you please let me know any suggestion to solve it.
Cheers,

for k=1:3
eval(sprintf('plot(D%d)',k))
hold on
end

Jamaledin, using several variables is not a good idea. you can create one variable
v=[D1;D2;...]
or a cell array
v={D1 D2 ...]
Look at this link http://matlab.wikia.com/wiki/FAQ#How_can_I_create_variables_A1.2C_A2.2C....2CA10_in_a_loop.3F

Many thanks for your support Azzi. Your recommendation is completely right. I redefined the arrays as follows and It works:
for i=1:11 D{i} = a(6+L(1,i):5+L(1,(i+1)),:); end
plot(D{i}(:,11),D{i}(:,1),'linewidth',1)
Many thanks for your replies. Best Regards, Jamaledin
