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 *
