Hello everyone,
I have an axis, suppose,
0_____________________10_____________________20
I have to define a vector x, such that from 0 to 10, I have to keep a step size dx0 and from 10 to 20, the step size should be dx1. Could anybody suggest how to handle it ? This vectoe x will be provided via 'for' loop to the PDE to be solved.

as simple as this :
dx0 = 1;
dx1 = 2;
x = [(1:dx0:10) (10+dx1:dx1:20)];
