AS FOR GIVEN DATA...
a) Compute ||Alls (Frobenius norm).All and ||Alli (by hand
SOL ::-)The Forbenius norm is
||A||Fr =
=( |2|2 + |2|2 + |1|2 + |8|2 + |2|2 + |8|2 + |-4|2 + |-6|2 + |13|2 )½
=(4+4+1+64+4+64+16+36+169)^1/2
=(362)½
=19.026
The -norm is
||A|| =
|
aij | , the maximum of the row sums
= max{ |2| + |2| + |1|, |8| + |2| + |8|, |-4| + |-6| + |13| } =
max{ 5,18,23 } = 23
The 1-norm is
||A||1 = |
aij | , the maximum of the column sums
= max{ |2| + |8| + |-4|, |2| + |2| + |-6|, |1| + |8| + |13| } = max{ 14, 10, 22 } = 22
b) Compute A and the norms ||All2 and |A
SOL ::-
for inverse of matrixA
A=[2 2 1;8 2 8;-4 -6 13]
X=inv(A)
For norm-2
n=norm(A)
For norm-2 of inverse of matrix A
A=inv(sym(magic(3)))
norm2=norm(A)
c) Use MATLAB to compute the condition number in norm-2 of A, based on your results 112 in MATLAB. from ). Verify your results in MATLAB using the cond command
SOL ::-
for computing the 2-norm condition number of the inverse of the matrix A
A=inv(sym(magic(3)));
condN2=cond(A)
