It is very unclear what you're trying to do, but it looks like you have a cell array A which is a vector of length n, and you want to have variables a1, a2, ..., an representing each element of your cell array. Is this correct? If so, don't do this. It is much better to keep your data in a cell array A and refer to it as A{i} rather than ai. Perhaps you should refer to http://matlab.wikia.com/wiki/FAQ#How_can_I_create_variables_A1.2C_A2.2C....2CA10_in_a_loop.3F.

Error in "maximum_life" at line 24,
variable A - undefined.
Her need defined.

i.e. you have do define A (and N) before calling ai = A(1:N);
otherwise is the same as saying "tell me the true lottery numbers that are gonna be drawn tomorrow"
