how to write a code for given equation? equation detail is given below.

i am trying to write the code but something being wrong so please help. code is here:

clc;
clear all;
A=5;
to=2;
tr=7;
T=10;
t=1:0.5:2;

for n=1:200;
   x(n) =(2*A*to/T*mod(sin(n*pi/T),(n*pi/T))*mod(sin(n*pi*tr/T),(n*pi*tr/T)))*cos(n*2*pi/T*t+pi/2);
end
plot(x)
and for more detail find attachment.

YOu RHS inside the loop is a vector of size 1X3, so you cannot save it into a vector. You need to rethink on your code.
