A matrix AA is negative definite if xTAx<0xTAx<0 for every non-zero vector xx. Negative definite matrices are exactly those matrices whose eigenvalues are all real and negative. 🙋 As we can see in the definitions above, a matrix cannot be simultaneously positive and negative definite, but...

(that’s really long time ago :-). If we invert the matrix A, the matrix equation Ax = b can be written as x = bA-1. That means multiplying the solution vector by the inverse of A yields the result for the x vector. According to Cramer the inverse matrix can be calculated by ...
