How to call variables with consecutive names?

Hello

If I have a number of variables with consecutive names e.g.

    var1, var2, var3...,  varn

and I want to do the same thing to all of them, how can I call them?

e.g.

for i = 1:n
  do something to vari
end

I have tried

for i = 1:n
  str = 'var%d';
  data = sprintf(st,i);
  do something to data
end

but this obviously give me data as a char variable and not the value of vari .

Thank you in advance!

Don't do it. Just use an array. It is what they are for.

var(1), var(2), var(3), etc

or if you have different sized variables use a cell array:

var{1}, var{2}, var{3}, etc

Alternatively you can use a struct if you really want loads of field names as e.g

myStruct.( sprintf( 'var%d', 1 ) );
myStruct.( sprintf( 'var%d', 2 ) );
