t = 0,0.001,1; % The commas can be read kind of like "t has the values 0 and 0.001 and 1".
What you need to do instead is use colons
t = 0:0.001:1; % The colons can be read kind of like "t is all the values spanning 0 to 1 in increments of 0.001"

mmmm....I hate to let the cat out of the bag too easily on homework; would prefer the student find the issue themselves with a little a hint as possible. The learning experience tends to be enhanced that'a'way.

Check what your t actually is (instead of what you intend it to be)...
