- SVD( <Matrix> )
- Returns the Singular Value Decomposition of the matrix (as a list of 3 matrices).
- Example:
SVD[{{3, 1, 1}, {-1, 3, 1}}]yields a list containing \left(\begin{array}{}-0.71&0.71\\0.71&0.71\\\end{array}\right) , \left(\begin{array}{}3.16&0\\0&3.46\\\end{array}\right), \left(\begin{array}{}-0.89&0.41\\0.45&0.82\\0&0.41\\\end{array}\right).
Note: This command is also supported in the 
CAS View. The numbers in the answer may vary in order between the 
Algebra View and CAS View.
CAS View. The numbers in the answer may vary in order between the Algebra View and CAS View.
