The scale data structure

Description

• 

The scale data structure is used to represent asymptotic scales (see MultiSeries for a definition).

• 

A scale is represented as a table whose entries are:

'list'

The ordered list of functions in the scale;

'variable'

the name of the first function having entered the scale;

'varname'

the name of the variable given by the user;

'back'

the expression of this variable in terms of 'variable';

'log'

a table of the logarithms of the functions in the scale.

• 

The functions in the scale are represented using the global name _var with three arguments. Thus,  means that the function occurs in an expansion in the variable  at the point , and  is the expression of the function.

• 

Scales being stored as tables, they can be extended during a computation.

• 

Currently, only operations between multiseries expressed in the same scale are supported.
