random gaussian noise with zero mean and unity variance

Subscript indices must either be real positive integers or logicals.

Error in fffff

kk1=kk1(1+(0.1).*array_gaussian_noise);

You are probably missing a multiplication (or other) operator.

Try this:

kk1 = kk1.*(1+(0.1).*array_gaussian_noise);
