WebLong story short, multiplying by a scalar on an entire matrix, multiplies each row by that scalar, so the more rows it has (or the bigger the size of the square matrix), the more times you are multiplying by that scalar. Example, if A is 3x3, and Det (A) = 5, B=2A, then Det (B) = 2^3*5=40. Det (kA)=k^n*Det (A). 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. WebJan 14, 2016 · Also, the matrix must be of full rank.
