deff
on-line definition of function
Calling Sequence
deff('[s1, s2, ...] = newfunction(e1, e2, ...)',text [,opt])
Arguments
- e1, e2, ...
input variables.
- s1, s2, ...
output variables.
- text
a matrix of character strings.
- opt
an optional character string:
- 'c'
function is "compiled" to be more efficient (default);
- 'p'
function is "compiled" and prepared for profiling (see help profile);
- 'n'
function is not "compiled".
Description
deff
can be used to define functions from sequences of instructions
written in text strings. The resulting function object has the same properties
of any other function defined in a text file and loaded with exec
.
Quotes in the instructions (delimiting strings or meaning matrix transposition)
have to be doubled to be interpreted correctly (see help quote). This can make
writing up a little awkward.
An option in such cases is to define functions in files as usual, to load them into
Scilab by exec
(with the 'n'
option) and to use
sci2exp
to get a printout of 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'])
