Function: algsqr
Section: algebras
C-Name: algsqr
Prototype: GG
Help: algsqr(al,x): element x^2 in al.
Doc: Given an element $x$ in \var{al}, computes its square $x^2$ in the
 algebra \var{al}.
 \bprog
 ? A = alginit(nfinit(y), [-1,-1]);
 ? algsqr(A,[1,0,2,0]~)
 %2 = [-3, 0, 4, 0]~
 @eprog

 Also accepts a square matrix with coefficients in \var{al}.
