Yesterday, I use the PDE toolbox of Matlab solve some PDE, it is very interesting, but seemly, only 2-dimension it works. In fact, I want to use it for equation like $$ u_t=u_{xx}+V(x)u $$ I can't found it how to work on 1-dimension domain, so I use it as picture below, it work well, but I can't get a 1-dimension picture which I want to use in my work. How should I do it ? I want the picture like the second picture below . Thanks for any help.
