MATLAB: How a solution depends on a variable

Question

I have a function UE=Explicit(S,sigma,r,T,M,K,gamma,N); and I want to plot how the solution depends on gamma where 0.5<=gamma<=1. All of the other parameters are constants. How can I do this?

Answer 1

One approach:

gammav = linspace(0.5, 1, 10);
for k = 1:numel(gammav)
    UE{k} = Explicit(S,sigma,r,T,M,K,gammav(k),N);
end

I have no idea what ‘Explicit’ is or what it produces, so it could be possible to vectorise this (instead of using the loop) depending on how you wrote the function. I am also saving each iteration to a cell array for that reason.

EDIT —

Plotting it depends on what ‘UE’ is. If ‘Explicit’ produces a scalar, this works:

figure
plot(gammav, [UE{:}])
grid

If it produces vectors or matrices, it will be necessary to use other approaches.
