Expandwrt

Function: expandwrt (<expr>, <x_1>, ..., <x_n>) Expands expression expr with respect to the variables <x_1>, ..., <x_n>. All products involving the variables appear explicitly. The form returned will be free of products of sums of expressions that are not free of the variables. <x_1>, ..., <x_n> may be variables, operators, or expressions.

expandwrt((1-a) * (1+z), z);
expandwrt(2 * (1-a*z), z);
expandwrt((1-a) * (1-z), z);
expandwrt(2 * (1+a*z), z);
H4: G*(z-1)*(z+1) / ((z-%i*r)*(z+%i*r));

By default, denominators are not expanded, but this can be controlled by means of the switch expandwrt_denom.

This function is autoloaded from simplification/stopex.mac.

There are also some inexact matches for expandwrt. Try ?? expandwrt to see them.
