Hi, I'm trying to generate a function for a sequence like:
x(n)={ sin(0.2*n),n>10 n is between 0 and 20
0,n<=10
I tried to solve the problem but only the ramp example came to my mind at this moment like x=sin(0.2*(n>10)) which is an complete incorrect solution.

Hi,
One way to generate the sequence is to use relational operators to assign values to variable 'x'. Following lines of code shows the same.
n=0:20;
x(n>10)= sin(0.2*n(n>10));
x(n<=10)= 0;
Pleasre refer this documentation to read more on how to filter elements of an array by applying conditions to the array.
