How to create an array containing all possible combinations of 0's and 1's to length n
n = 3 c = arrayfun(@(k) mat2cell(dec2bin(0:2^k-1)-'0', ones(2^k,1), k), 1:n, 'un', 0) c = vertcat(c{:})

I try to optimalize a temperature when looking at different concentrations for a chemical reaction. I get a good plot for values of k from 1 tot 70 but when going higher it won't work anymore. I don't know what to do, anyone?
You should reset t(1) to zero before the inner loop. You might not even need a vector t. Just use t = t + tstep, as you only use...

Is it possible to do this without for cycle?
