Hi... How can I change a string with a loop number?

for example,

if we have

x='function#';

for i=1:10

Do something (function1=..., function2=..) and so on

end

I want to change # (the last letter of function#) by the loop number(i=1:10)

I use the function

strrep(x,'#',i)

but it does not wrok

Thanks

But , I do not want to create it intentionally, It is the other software which takes input in the same way of string

parag patil, please clarify how you're calling this "other software" and what it expects its inputs to be.

If it expects text data, perhaps a file name, that you can create using sprintf or num2str. [In the specific case of file names, you can get a list of files in the directory using dir.] If it expects variables that you've created using sequential names, see Stephen's answer for reasons why this is a bad idea.
