Given the following matrix A$,$ calculate its null space using Python Numpy's Singular

Value Decomposition $($SVD$)$ method.

$=[$

$123$

$456$

$789$

$]$

Hint $1$: Use the following command: $..(),$ and note that the null space can

be computed from the $()=$

$$ by locating the last row of VT

or last column of

V corresponding to the smallest singular value of $.$

Hint $2$: Check the obtained null space vector$($s$)$ by applying the Null space definition

$=0$
