%th

Maxima Function

Calling Sequence

%th (i)

Description

The value of the i'th previous output expression. That is, if the next expression to be computed is the n'th output, %th (m) is the (n - m)'th output.

%th is useful in batch files or for referring to a group of output expressions. For example,

block (s: 0, for i:1 thru 10 do s: s + %th (i))$

sets s to the sum of the last ten output expressions.

%th is recognized by batch and load. In a file processed by batch, %th has the same meaning as at the interactive prompt. In a file processed by load, %th refers to output expressions most recently computed at the interactive prompt or in a batch file; %th does not refer to output expressions in the file being processed.
