#### D.3.1.9 power

Procedure from library `matrix.lib` (see matrix_lib).

Usage:
  power(A,n); A a square-matrix of type intmat or matrix, n=integer>=0

Return:
  intmat resp. matrix, the n-th power of A

Note:
  for A=intmat and big n the result may be wrong because of int overflow

Example:

    LIB "matrix.lib";
    intmat A[3][3]=1,2,3,4,5,6,7,8,9;
    print(power(A,3));"";
    ==>    468   576   684
    ==>   1062  1305  1548
    ==>   1656  2034  2412
    ==>
    ring r=0,(x,y,z),dp;
    matrix B[3][3]=0,x,y,z,0,0,y,z,0;
    print(power(B,3));"";
    ==> yz2,    xy2+x2z,y3+xyz,
    ==> y2z+xz2,yz2,    0,
    ==> y3+xyz, y2z+xz2,yz2
