How to create semi-infinite solid in MATLAB?

  1. Mar 9, 2012 #1
    Hello,
    Am working on a model that involves heat conduction in a semi-infinite solid. I have been using linspace() command for finite geometry, but now i need to create a 1-dimensional semi-infinite solid. Any suggestions?
    Thank you.

    In numerical simulations, we can refer to infinity as something very far from the disturbance. In your case, if the heat conduction only takes place e.g from 0 to 1, you can set a linespace from 0 to 10 or 20, and it will effectively work as theoretical infinity would.
