Ran in:
f=@(x) exp(x)-x.^2+5*x;
x=1:0.1:10;
y=f(x);
d=gradient(y, x);
plot(x,d,'o')

which gradient
The output will likely show you the name of a file that is not provided by Mathworks. You need to rename or delete that file.
If it does happen to show a file provided by Mathworks such as toolbox/matlab/datafun/gradient.m then you would have a corrupt version of the file and would need to be reinstalled.
