Description

A library is a data type with type number 14. It contains a path-name and a set of names. It allows automatic loading of variables using the following algorithm:

Suppose the Scilab user references the variable named foo. Scilab first looks if foo is the name of a primitive or of an already defined variable. If not, it looks for foo sequentially (the newest first) in all defined library .

Suppose foo belongs to the set of names of the library xlib then Scilab tries to load the file <xlib-path-name>/foo.bin. <xlib-path-name>/foo.bin must have been created using the save function

Library are often used for collection of functions, but they can also be used for any collection of scilab variables

If a function is defined in more than one library, the default search algorithm loads thode contained in the newest. It possible to force the use of a specific library using dot notation:

xlib.foo loads the variable foo contained in xlib. if foo is a function and xlib.foo(args) executes the functions

Examples

// elemlib is a predefined library
elemlib //displays the contents of the library
A=rand(3,3);
cosm(A) //loads cosm and executes it

who // now cosm is a variable

elemlib.sinm //loads sinm from the library

elemlib.cosm(A) //reloads cosm and executes it
