subexpr
Rewrite symbolic expression in terms of common subexpressions
Description
[
is
equivalent to r
,var
]
= subexpr(expr
,var
)[r,var] = subexpr(expr,'var')
, except
that the symbolic variable var
must already exist
in the MATLAB® workspace.
This syntax overwrites the value of the variable var
with
the common subexpression found in expr
. To avoid
overwriting the value of var
, use another variable
name as the second output argument. For example, use [r,var1]
= subexpr(expr,var)
.
