Question

Number 15...

Here is what I've tried, but I get a warning after entering VA*V . Could it probably be becauseof the generalized eigenvector or am I doing this the wrong way?

>> A= [1 4 -1 2, 0 3 1 4, 0 0 1 0, 0 0 2 -3]
>> [V,D] = eig(a)
>> VA*V

Please help me I need the code.

Explanation / Answer

this is the code. ---------------------------------------------------------------------------------------- A= [1 4 -1 2; 0 3 1 4; 0 0 1 0; 0 0 2 -3] [V,D] = eig(A) c=inv(V) d=c*A e=d*V _________________________________________________________________ and here is the output what i found. A = 1 4 -1 2 0 3 1 4 0 0 1 0 0 0 2 -3 V = 1.0000 0.8944 0.1374 1.0000 0 0.4472 -0.5494 -0.0000 0 0 0 0.0000 0 0 0.8242 0.0000 D = 1 0 0 0 0 3 0 0 0 0 -3 0 0 0 0 1 Warning: Matrix is close to singular or badly scaled.
