Calling variables into objective function

I want to use the optimization toolbox with a vectorized objective function. The objective function will be vector and matrix multiplication. I have the matrices that should be used, but they are 18x18. I also want to run a variety of different tests using different matrices. What is the best way to do this? I think I will have to just set up the matrix in each version of the objective function. It would be nice for there to be a way to read an excel file in the main optimization m file, and call the variable into the supporting functions, but I don't think there is, right?

There is, but the far better way is to use anonymous or nested functions, as covered here
