↓MATCH
Type: Command
Description: Match Pattern Down Command: Rewrites an expression that matches a specified pattern.
↓MATCH rewrites expressions or subexpressions that match a specified pattern
'symb
pat
'. An
optional condition,
'symb
cond
', can further restrict whether a rewrite occurs. A test result is also
returned to indicate if command execution produced a rewrite; 1 if it did, 0 if it did not.
The pattern
'symb
pat
' and replacement 'symb
repl
' can be normal expressions; for example, you can
replace .5 with
'SIN(π/6)'. You can also use a “wildcard” in the pattern (to match any
subexpression) and in the replacement (to represent that expression). A wildcard is a name that
begins with &, such as the name
'&A', used in replacing 'SIN(&A+&B)' with
