Diagonal of a vector

WebSo this quantity here has the property that for example, the diagonal element or the first diagonal element is expected value of x1- mu 1 squared. Okay. So it's just the ordinary variance of the first element of the vector. The second entry, second diagonal entry of this matrix is just the expected value of X 2 minus mu 2 squared. WebIf you know the dimensions of your matrix (square or otherwise), you can extract any diagonal you like, or even modified diagonals (such as numbers in (1,1), (2,3), (3,5), etc), somewhat faster than using diag, by simply using an index call like this: a=M (1:4:9) (note: this produces a row vector; for a column vector, just transpose) For an NxN ...
