The technique I always use is to create an anonymous function, outlined at mathworks here. This saves any hassle trying to do what you are doing. The link is in the context of root finding, but the same principles apply.

The 4th input parameter is for options to the solver and optional arguments start at the fifth input. You can easily fix this by passing an empty [] matrix as the 4th input.

You can properly typeset code using the curly braces option {}. This corresponds to putting the code between ` marks inline and indenting by four spaces for block code.
