macro
Scilab procedure and Scilab object
Description
Macros are Scilab procedures ("macro", "function" and "procedure"
have the save meaning). Usually, they are defined
in files with an editor and loaded into Scilab by exec
or through
a library.
They can also be defined on-line (see deff). A file which contains a macro must begin as follows:
function [y1, ..., yn]=foo(x1, ...,xm)
The yi
are output variables calculated as functions of
input variables and variables existing in Scilab
when the macro is executed.
A macro can be compiled for faster execution. Collections
of macros can be collected in libraries.
Macros which begin with %
sign (e.g. %foo
) and whose
arguments are lists are used to perform specific
operations: for example, z=%rmr(x,y)
is equivalent
to z=x*y
when x
and z
are rationals
(i.e. x=list('r',n,d,[])
with n
and d
polynomials).
