Hello everyone
Below is code that i want to run for different duration. What actually effects the lenght in below code. I thought N changes number of code bit it does not changes with any value of N. If i have to run it for long what should i change?
Code is pasted in above line. Thats how time is defined in my long code. Last two lines dummy plot just to show signal.

What does the following two lines in your code mean?
These lines must return error.
wu 1.2868e + = 04;
and
time = time T * / N;

I dont know why some symbols change when i save my posts. Its wu = 1.2868e + 04; and time = T * time / N;
wu 1.2868e + = 04;
T = 10 / wu;
N = 200;
time = 1: 1: N;
time = time T * / N;
% above is how time is defined in my long code, i cant change
% below is just a random signal defined to show
x = sin (2 * 8000 * time);
plot (time, x);

wu=1.2868e4;
T=20/wu;%change T
N=200;
t=1:N;
t=T*t/N;
x=sin(16000*t);
plot(t,x);
