find infinity norm of a polynomial

 Calling Sequence maxnorm(a)

Parameters

 a - expanded polynomial with integer, rational, floating-point, or complex coefficients

Description

 • The maxnorm(a) function computes the maximum of the absolute values of the coefficients of a.
 • For complex coefficients, the maxnorm routine finds the maximum of the absolute values of the real and imaginary parts.

Thread Safety

 • The maxnorm command is thread-safe as of Maple 15.
 • For more information on thread safety, see index/threadsafe.

Examples

 > $\mathrm{maxnorm}\left(x-3y\right)$
 ${3}$ (1)
 > $\mathrm{maxnorm}\left(\left(3-4I\right)x-3Iy\right)$
