I am using fminsearch to optimize a function, but some variables are not part of the objective function. Currently I pass the "data" as global variables, but I am wondering if there is a better way to do this.

For example, say I have a function that I want to optimize as follows:

f = fun(x0, data);

I want to find the values of x0 that minimize f, but I need to provide additional "data" which does not change.

There are a couple of ways to do this. In the Help docs for fminsearch() there is a link to "Parameterizing Functions" that explains how to do this. See also Example 2 in the fminsearch documentation.
