SVD[ <Matrix> ]
Returns the 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 Menu view cas.svg CAS View. The numbers in the answer may vary in order between the Menu view algebra.svg Algebra View and Menu view cas.svg CAS View.
