Sum of the singular values of a random matrix

Beginning status (before activations):

   1 *
   2 *m=100
   3 *MAT A=ZER(m,m)
   4 *MAT #TRANSFORM A BY rand(2001)
   5 *MAT SVD OF A TO U,D,V / Singular value decomposition
   6 *MAT S=SUM(D)
   7 *MAT_S(1,1)=
   8 *

Ending status (after activations):

   1 *
   2 *m=100
   3 *MAT A=ZER(m,m)
   4 *MAT #TRANSFORM A BY rand(2001)         / *A~T(A_by_rand(2001)) 100*100
   5 *MAT SVD OF A TO U,D,V / Singular value decomposition
   6 *MAT S=SUM(D)       / *S~SUM(Dsvd(T(A_by_rand(2001)))) D1*1
   7 *MAT_S(1,1)=292.54234730964
   8 *
