Description

Some predefined variables names begin with %, such as%i (for sqrt(-1)), %inf (for Infinity), %pi (for 3.14...),%T (for the boolean constant "true"),...

In addition, functions whose names begin with % are special : they are used for primitives and operators overloading (see overloading).

For example the function %rmr performs the multiplication (m) operation x*y for x and y rational matrices (r). The coding conventions are given by the readme file in directory SCI/modules/overloading/macros.

Examples

x1=tlist('x',1,2); x2=tlist('x',2,3); deff('x=%xmx(x1,x2)','x=list(''x'',x1(2)*x2(2),x2(3)x2(3))'); x1x2
