String to variable name MATLAB -

-

if instance have variable xa=2, , construct string joining 'x' , 'a', how can make new string have value 2?

xa=2; var=strcat('x','a');

the result of var=xa, want var=2.

thank you

use eval():

var = eval(strcat('x','a'));

it "evaluate" string 'xa' , translate value of variable xa.
