Function: isolate (<expr>, <x>) Returns <expr> with subexpressions which are sums and which do not contain <var> replaced by intermediate expression labels (these being atomic symbols like
%t2, ...). This is often useful to avoid unnecessary expansion of subexpressions which dont contain the variable of interest. Since the intermediate labels are bound to the subexpressions they can all be substituted back by evaluating the expression in which they occur.
exptisolate (default value:
true will cause
isolate to examine exponents of atoms (like
%e) which contain <var>.
isolate will also isolate with respect to products. See
example (isolate) for examples.
There are also some inexact matches for
?? isolate to see them.
