Output matrix for simple function

I'm brand new to Matlab, and have created a very simple function here to calculate an ion's equilibrium potential:
function y = equipotent(n,X1,X2)
y = (58/n) * log10(X1/X2);
I'd like to do two things: 1) vary X2 for a set of values (1-100) while keeping X1 and n constant. and 2) store all the outputs from the function in a vector for plotting X2 vs y.
Anything helps! Thanks!

If you change your code to
function y = equipotent(n,X1,X2)
y = (58/n) * log10(X1./X2);
then it will give a vector output y for vector input X2, and you should be all set.

Hi Derek,
MATLAB has some useful ways to do what you're trying to do. If you use the (.*) operator instead of (*), it will perform a vector multiplication.
Therefore you can adjust your function as follows:
function y = equipotent(n,X1,X2)
y = (58 ./ n) .* log10(X1 ./ X2);
Then you can just run commands:
y = equipotent(4, 3, X2)
figure
plot(X2,y)
Did that help you out?
