getf — defining a function from a file
getf(file-name [,opt])
Scilab string.
optional character string
loaded functions are "compiled" to be more efficient (default)
loaded functions are not "compiled"
loaded functions are "compiled" and prepared for profiling (see profile)
WARNING: this function has been deprecated (see exec as a replacement of getf). getf will be removed in Scilab 5.3
loads one or several functions (see functions)
    defined in the file 'file-name'. The string
    opt='n' means that the functions are not compiled
    (pre-interpreted) when loaded. This can be useful for some debugging
    purpose (see comp). By default, functions are compiled
    when loaded (i.e. opt='c' is used).
In the file a function must begin by a "syntax definition" line as follows:
function [y1,...,yn]=foo(x1,...,xm)
The following lines contain a sequence of scilab instructions.
The "syntax definition" line gives the "full" calling syntax of this
    function. The yi are output variables calculated as
    functions of input variables xi and variables existing
    in Scilab when the function is executed. Shorter input or output argument
    list may be used.
Many functions may be written in the same file. A function is
    terminated by an endfunction keyword. For compatibility
    with previous versions a function may also be terminated by the following
    function keyword or the EOF mark.
    For that reason it is not possible to load function containing nested
    function definition using the getf function.
getf is an obsolete way for loading functions
    into scilab from a file. It is replaced by the function exec. Note that functions in a file should be
    terminated by an endfunction keyword. The
    exec function supposes
    opt=='c'.
To prepare a function for profiling please use the add_profiling function.
