WebA square matrix A is invertible if and only if its determinant is not zero, and its inverse is obtained by multiplying the adjoint of A by (det A) −1. [Note: A matrix whose determinant is 0 is said to be singular; therefore, a matrix is invertible if and only if it is nonsingular.] WebWhen a matrix transforms any vector v to 0, it means it is singular. So here (A-λI) is singular which means det of (A-λI) is 0. This holds true for ALL A which has λ as its eigenvalue. floating u shelves measurementshttp://www.ece.northwestern.edu/local-apps/matlabhelp/techdoc/ref/det.html floating uterus theory

"WebUsing det (X) == 0 as a test for matrix singularity is appropriate only for matrices of modest order with small integer entries. Testing singularity using abs (det (X)) <= tolerance is not recommended as it is difficult to choose the correct tolerance. The function cond (X) can check for singular and nearly singular matrices.
