deff Scilab Group Scilab Function deff
NAME
deff - on-line definition of function
CALLING SEQUENCE
deff('[s1,s2,...]=newfunction(e1,e2,....)',text [,opt])
PARAMETERS
e1,e2,..., : input variables.
s1,s2,..., : output variables.
text : matrix of character strings
opt : optional character string
'c' : function is "compiled" to be more efficient
(default)
'n' : function is not "compiled"
DESCRIPTION
On-line definition of function (user defined function): the name of the
created function is newfunction. text is a sequence of instructions
usually set as a vector of character strings.
This command can be used inside a function and the new function can be an
input or output of any other function.
Usually, functions are defined in a file and loaded into Scilab by getf
Some time, in particular when you want to use define strings within deff
text is rather difficult to write. A more tractable way may be to define
your function in a file as usual, to load it into Scilab by getf (without
'c' option) and use sci2exp to get corresponding deff instructions.
EXAMPLES
deff('[x]=myplus(y,z)','x=y+z')
//
deff('[x]=mymacro(y,z)',['a=3*y+1'; 'x=a*z+y'])
SEE ALSO
getf, comp, exec, function
