How did you ever get in the unfortunate position of having 1000 variables all with different names ? Did you not heed the FAQ's advice against doing that: http://matlab.wikia.com/wiki/FAQ#How_can_I_create_variables_A1.2C_A2.2C....2CA10_in_a_loop.3F If so, you'll have to use the hated eval() function.
