Compute Condition Number of Hilbert Matrix
Hilbert matrices are examples of ill-conditioned matrices.
Numerically compute the condition numbers of the 3-by-3 Hilbert matrix by using
cond and vpa.
Condition number of a matrix is the ratio of the largest singular value
of that matrix to the smallest singular value. The P-norm condition
number of the matrix A is defined as
norm(A,P)*norm(inv(A),P).
Tips
Calling cond for a numeric matrix that is not a symbolic object
invokes the MATLAB®cond function.
