Atomic Variables

Maple has two basic types of subscripts in 2-D math, index subscripts and literal subscripts. Use an index subscript to form an indexed name.  The indexed name ab is equivalent to a[b].  Indexed names are used to refer to the bth element of an object a.

Use a literal subscript to form a name that will not be interpreted as an index of any kind. For example, if you want to use both x and x0 in a worksheet as distinct names, use a literal subscript for x0.

Terms with literal subscripts are one variant of atomic variables.  For more information on atomic variables, see Atomic Variables Details.

Control Formatting of Atomic Variables

You can switch the formatting of atomic variables on and off. When the formatting is turned on, atomic variables are displayed in a purple font color (for example x0, distinguishing them from index subscripts. When the formatting is turned off, the atomic variables are displayed in black.

To switch the formatting of atomic variables on:

• 

From the View menu, select the Atomic Variables option.

  

Atomic variable formatting is now turned on for your worksheet.

To switch the formatting of atomic variables off:

• 

From the View menu, clear the Atomic Variables option.

  

Atomic variable formatting is now turned off for your worksheet.

Note: By default, atomic variable formatting is turned off.

You can also modify the font styles used for atomic variables by changing the Atomic Variable style set.

To modify the font or color used for atomic variables:

1. 

From the Format menu, select Styles.
