convert/elsymfun

 Calling Sequence convert( p, 'elsymfun' )

Parameters

 p - a symmetric polynomial; the expression to be converted

Description

 • The convert( p, 'elsymfun' ) command converts the input polynomial to an expression in terms of the elementary symmetric functions.
 • If the input polynomial is not symmetric, then an exception is raised.

Examples

 > $\mathrm{convert}\left({x}^{3}+{y}^{3}+{z}^{3},'\mathrm{elsymfun}'\right)$
 ${\left({x}{+}{y}{+}{z}\right)}^{{3}}{-}{3}{}\left({x}{+}{y}{+}{z}\right){}\left({x}{}{y}{+}{x}{}{z}{+}{y}{}{z}\right){+}{3}{}{x}{}{y}{}{z}$ (1)
 > $\mathrm{convert}\left({\left(x+y\right)}^{2}+{\left(x+z\right)}^{2}+{\left(z+y\right)}^{2},'\mathrm{elsymfun}'\right)$
 ${2}{}{\left({x}{+}{y}{+}{z}\right)}^{{2}}{-}{2}{}{x}{}{y}{-}{2}{}{x}{}{z}{-}{2}{}{y}{}{z}$ (2)
 > $\mathrm{convert}\left(x-y,'\mathrm{elsymfun}'\right)$
