FREEMAT EXAMPLES PDF

Getting Help There are three sources of help beyond the user manual, of course. A Google Group has been set up for support. It is open to anyone to join and read, but you must be a member to post, and posts are moderated necessary after the spam-bots took over the old sourceforge mailing list. The e-mail address for the group is freemat googlegroups. What is FreeMat?

Also, when keywords see help keywords are used, an arbitrary subset of the parameters may be unspecified. Similarly, the function can create a cell array named varargout for variable length output lists. Also, FreeMat works like C in that the caller does not have to supply the full list of arguments.

These exam;les functions that can only be called by other functions in the same. However, the second call succeeds, and note that arg1 has now changed. As variable argument and return functions are covered elsewhere, as are keywords, we include one final example that demonstrates the use of helper functions, or local functions, where multiple function declarations occur in the same file.

See help for nargin examplrs nargout for more details. Sunday, October 25, See help varargin and varargout for more details. That means that variables defined or modified inside a function do not affect the scope of the caller. To assist in deciphering the exact parameters that were passed, FreeMat also defines two variables inside the function context: So, for example, if the file is named foo. Inside the function, varargin is a cell-array that contains all arguments passed to the function that have not already been accounted for.

Note that the name of the file and not the function name fname used in the declaration is how the function appears exanples FreeMat. The flip side of this fact is that functions are harder to debug than scripts without using the examlles function, because the intermediate calculations used in the function are not available once the function exits. The most general syntax for a function declaration is the following: In these cases, the last argument to the parameter list is the special argument varargin.

A first attempt at doing so has no effect: Note that this is only true freemmat the first function that appears in a. We can change that by passing the first argument by reference: For functions with a fixed number of input or output parameters, the syntax is freemst simpler: Additional functions that appear after the first function are known as helper functions or local functions. Examples Here is an example of a trivial function that adds its first argument to twice its second argument: Another important feature of functions, as opposed to, say scriptsis that they have their own scope.

Page Last Updated on: Furthermore the names of these helper functions are determined by their declaration and not by the name of the. In some circumstances, it is necessary to have functions that take a variable number of arguments, or that return a variable number of results. Related Posts.
