FREEMAT EXAMPLES PDF

The main Web site for FreeMat is hosted on SourceForge. For example, if you want to find the volume of a cube of side length 3, you could so. Note the following behavior differences between MATLABs regexp and FreeMats : • If you have an old version of pcre installed, then named. There are several forms for function declarations in FreeMat. The most general An example of using helper functions is included in the examples. Another.

Note that this is only true for the first function that appears in a. So, for example, if the file is named foo. A first attempt at doing so has no effect: That means that a function can freely exakples and use variables without unintentionally using a variable name reserved elsewhere.

In some circumstances, it is necessary to have functions that take a variable number of arguments, or that return a variable number of results. To assist in deciphering the exact parameters that were passed, FreeMat also defines two variables inside the function context: Also, FreeMat works like C in that the caller does not have to supply the full list of arguments.

Examples Here is an example of a trivial function that adds its first argument to twice its second argument: That means that variables fteemat or modified inside a function do not affect the scope of the caller.

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. 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.

The flip side of this fact is that functions are harder to debug than scripts without using the keyboard function, because the intermediate calculations used in the function are not available once the function exits.

Page Last Updated on: Additional functions that appear after the first function are known as helper functions exaples local functions. The function name fname can be any legal FreeMat identifier.

These are functions that can only be called by other functions in the same. Furthermore the names of these helper functions are determined by their declaration and not by the name of the. However, the second call succeeds, and note that arg1 examles now changed.

Functions are stored in files with the. For functions with a fixed number of input or output parameters, the syntax is somewhat simpler: Note that the name of the file and not the function name fname used in the feeemat is how the function appears in FreeMat.

An example of using helper functions is included in the examples. Sunday, October 25, Inside the function, varargin is a cell-array that contains all arguments passed to the function that have not already been accounted for. See help varargin and varargout for more details.

See help for nargin and nargout for more details. We can change that by passing the first argument by reference: 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. Another important feature of functions, as opposed to, say scriptsis that they have their own scope.
