Determinant of a big matrix
Webter how big a matrix is? I bring to mind a question from the midterm exam. Namely: Suppose that a vector ~t 0 represents a temperature state of a discretely approximated system at time 0. Then there is a matrix M and a vector ~bsuch that the temperature distribution an hour later is represented by ~t 1 = M ~t+ b: In our example, we had M= 2 … WebOct 13, 2024 · Testing for a zero determinant. Look at what always happens when c=a. Disaster for invertibility. The determinant for that kind of a matrix must always be zero. When you get an equation like this for a determinant, set it equal to zero and see what happens! Those are by definition a description of all your singular matrices.
