matlab: how can use variables value in variables name?

i want name variable using values of other variables given in function. so, if have values x1,x2 can make new variable's name as:

x_(x1's value)_(x2's value) name.

i've checked out eval, num2str, strcat functions, of yet can't make have variable name above can assign value to.

any appreciated.

take @ following faq:

• how can create variables a1, a2,...,a10 in loop?

it answers "how" part of question , recommends better approach using arrays.
