macro(1) Scilab Function macro(1)
NAME
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 getf 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).
