You have three options for what you use as the function definition line. Regardless of which option you use, the [[functional variable]] names must appear as outputs of the function. Rave will use the names of the function's outputs as the names of the corresponding [[functional variables]]. The name of the function itself (i.e. the .m file name) does not matter as long as it is a legal matlab function name (i.e. must begin with a letter and cannot contain spaces or symbols other than _ ).

==Variable Names as Inputs==

===Variable Names as Inputs===

You can use the input variable's names as the inputs to the function. An obvious constraint in this case is that the variable names must be legal MATLAB variable names. For example, the following function definition would work:

The order of the outputs matters insofar as any time Rave lists the variable names they will appear in the same order in which they appeared in the function definition.

==Single-Input Format==

===Single-Input Format===

An alternative option is to specify a single input to the function. When you import the function, Rave will ask which variables to use as inputs to the function. The actual input data that Rave sends the function will then be an array in which each column represents one variable in your [[data set]].
