I reduced you time vector
tx = [0 1]; % Time vector
and succeeded

I written that code from pdf file i have given. I am asking about the code is it right or not and I want to rescale the time is there any way to do that.

sumation of cos(n \Omega t) I have written is correct. I want to rescale time for lage value is it possible.

When I am giving time t=[0:1:20] the value of s1 is different then when I provide t=[0:0.1:20] what is the problem in code.
