**Diagonal Matrix- from Wolfram MathWorld**

Otherwise, if the condition is false then execute the else statement and print the given order is not square matrix. Another for loop is used to add the main diagonal of matrix as well as the opposite diagonal of the matrix.... sum(diag(a,2)) is summing the diagonal 2 away from the main diag, which has one entry, 3.

**How to create a diagonal matrix in R? Stack Overflow**

since if we use, for example, the Gaussian elimination to compute the inverse, we divide each row of the matrix ( A I ) by the corresponding diagonal element of A in which case the number 1 on the same row of the identity matrix on the right is also divided by the same element.... In this final post in the series I discuss the inverse of a block diagonal matrix. In particular I want to prove the following claim: If is a block diagonal matrix with submatrices on the diagonal then is invertible if and only if is invertible for . In this case is also a block diagonal matrix, identically partitioned to , with so that. Proof: This is an if and only if statement, so I have to

- Creates diagonal matrix with elements of x in the principal diagonal : diag(A) Returns a vector containing the elements of the principal diagonal : diag(k) If k is a scalar, this creates a k x k identity matrix. Go figure. solve(A, b) Returns vector x in the equation b = Ax (i.e., A-1 b) solve(A) Inverse of A where A is a square matrix. ginv(A) Moore-Penrose Generalized Inverse of A. ginv(A
- Let D be an nÃ—n diagonal matrix. Then its inverse is given by the reciprocals of the diagonal elements in the matrix provided that none of the diagonal elements are zero. If any of the diagonal elements are zero, D is not invertible.
