Dear All,

I want to learn the logic for the following in matlab.


y = x(1) - x(2) + x(3) - x(4) + .......

The expression you have given cannot be evaluated in matlab. The series must be finite.

You need to figure out the physical significance of the terms on the right hand side. A well written script has plenty of comments and with some basic idea, you should be able to figure out the physical meaning.

As written, it simply means the sum of the odd terms minus the sum of the even terms.
