What Is a Test Matrix

A test matrix is used to capture the actual quality, the effort, the plan, resources and time required to complete all phases of software testing. A coverage matrix, also known as a traceability matrix, maps the test cases and customer requirements.

What is non defective Matrix?

Non-defective matrices are precisely those matrices that have an eigenvalue decomposition. Theorem. A ∈ IRm×m is non-defective if and only if it has an eigenvalue. decomposition. A = XΛX−1 In view of this, another term for non-defective is diagonalizable.

For what values of A is the matrix defective?

If a matrix has an eigenvalue, then it has at least one eigenvector corresponding to that eigenvalue. So, yes, the only way it can be defective is if alpha=0 or alpha=2.
