Avoid such meta-programming. Guessing the names of the variables and construct some obscure EVAL command to access them increases the complexity of your program without any benefit.
If the variables belong together, define them as fields of a struct. Then dynamic field names allow a fast and save processing:
a.x = 1:10;
a.y = rand(10);
fields = fieldnames(a);
for k = 1:length(fields)

Try this out:
for k = 1:length(my_vars)
where value_to_assign is jsut that, the value you want the variable to have.

This variables are a matrixes, so I would like to call them directly by name in whos.
