WebA column vector is an m-by-1 matrix, a row vector is a 1-by-n matrix, and a scalar is a 1-by-1 matrix. To define a matrix manually, use square brackets [ ] to denote the beginning and end of the array. Within the brackets, use a semicolon ; to denote the end of a row. In the case of a scalar (1-by-1 matrix), the brackets are not required. WebNov 21, 2011 · To obtain your case, put a = 1 and b = 0. First proof. This works if c h a r ( K) = 0 or n is prime to c h a r ( K) > 0. If a = 0, then det A = b n. Suppose a ≠ 0 and consider the vector v = ( 1, …, 1) ∈ K n; it is clear that v is an eigenvector of A with eigenvalue α = ( n …
