Help with my code?

I'm trying to solve for a set of values ([0,6]) for my squared function, but it only returns an error about "subscript indices must either be real positive integers or logicals" Here is my code :

clear;
clc;
t=[0:6];
k=0.4;
NO2(t) = (0.5./(1+(0.5)*(k)*t));
NO2_Squared(t) =(NO2(t)).^2

You are using t as a subscript in these lines, and one of the t values is 0:

NO2(t) = (0.5./(1+(0.5)*(k)*t));
NO2_Squared(t) =(NO2(t)).^2

Simply drop those subscripts:

NO2 = (0.5./(1+(0.5)*(k)*t));
NO2_Squared =(NO2).^2;
