Im solving a ODE equation with ode15s in in space, voltage and time, with 801 nodes. How long should i expect matlab to take to solve this? Because at the moment it has been upwards of 20 minutes?

Could be hours. You might want to interrupt it and recode slightly with an options parameter that requests plotting as it goes so that you can see the progress.

notice the calling forms that have "options" as a parameter, and note "You can create options using the odeset function". Over at odeset, you want the "Solver Output Options" section, http://www.mathworks.com/help/matlab/ref/odeset.html#f92-1016858. You probably want 'OutputFcn', and you might want to use @odeplot as your choice. You might want to specify 'OutputSel' to be selective about what you plot.
