Hi AYAH,

why do you want to do this, you really might want to use a vector with X(1),X(2),...,X(10), they are dynamic in MatLab, so there is nothing to worry about this. And cases are really rare, in which you want to do what you'd like to have...

However, you can do it by using assignin, e.g. like that:

n=10;
for k=1:n
    varname=['X',num2str(k)];
    assignin('caller',varname,k)
end

Thank you very much

Hi Walter,

I faced problem on how to get the values in for_loop ,such like this:

for i=0:2:10

display X[i] %this statment wrong; how could I display x0 x2,x4,x6,x8

end

And I have another problem that I don't know how to save array of numbers on each variable such as x1=[1 2 4]

x2=[1 7 8 9 7]

[Walter Roberson]

If you want X0 onward, then

X{2}= [1 2 4];

X{3}= [1 7 8 9 7];

and

for i = 0:2:10

disp(X{i+1})

end

Thanks alot
