Simple Question ( for loop with differnt variables)

Heyho folks,

This is a really simple example for the Question I have.

for i=1:3
eval ( ['A' num2str(i) '=i'] )
end

generates A1 = 1 / A2 = 2 /A3 = 3

now i want to use these variables.....but how?

for i= 1:3
B = A{i} + 1
end %nope doesnt work

for i =1:3
B = ([A num2str(i)]) +1 
end %nope doesnt work

............

Why are you complicating things?

for i=1:3
    A(i)=i
end 
for i= 1:3
    B(i) = A(i) + 1
end

Well, the Problem is. This doesnt work.... I alraedy have the Variables A1 to A10 with Values. Now I want to use them as:

load('test.mat')
for i = 1:10
PlotData = A(i) % this is the important line
do some  math.
end

So it takes A1 calculates....takes A2 calculates....

for k=1:3
  eval(['data=' sprintf('A%d',k)])
  %do
end

If you want to use A1, A2, etc. you will have to continue using eval. I recommend switching to an array or cell array, or even a structure, in order to better access your data.
