I do not want to plot the 0 components of my vector; how do I remove these components without effecting the length of the vector?

Use Energy(Energy == 0) = NaN; It will not shorten the length of the vector, but will not be displayed on the graph.

If I am not mistaken, MATLAB can only make use of CUDA-capable (i.e. nvidia) GPUs.

solve() only gives one of infinitely many solutions.

Your mistake is that you applied == instead of =. Do this one: solution = solve('x*y=1','x','y');
