Hi
I have a simple function, for exemple:
[ax] = testthat(x,y)
I use this function a lot an need to create a different output name to [ax] for exemple first time the name shold be "a1" second time "b1"... and keep all these output variable availlable.
I try
al=('a':'z').';
[al(3) num2str(1)] = testthat(x,y)
But clearly it is not the good way to make it...

It is certainly "not the good way to make it", because there is no "good way to make it", because using dynamically named variables is very bad way to "make it", which unfortunately beginners seem to fall in love with.
Read this link to know why dynamically named variables is a slow, buggy and obfuscated way to program, and what much better alternatives there are:
Browsers: do not follow the accepted answer, read the link above to know why.

My pleasure.
I absolutely cannot understand why dynamic variables would be preferable to an array.

@Jonathan Roy: read this to know why dynamically named variables are a really bad way to program (no matter how much beginners love them):
You should have used either a cell array (as per Start Strider's answer) or a multidimensional array.

If you are doing it in a loop, subscript it as a cell array instead:
for k1 = ...
a{k1} = testthat(x,y);
end
That keeps everything in one array that you can easily work with elsewhere in your code.
It is not good programming practice to create dynamic variables, such as ‘a1’, ‘a2’ and so forth. They are difficult to work with.
