Syntax

c = diag(a)

c = diag(a, b)

Computes a diagonal matrix or the diagonal of a matrix. diag(a, 0) is equivalent to diag(a).

Name	Description
a	Specifies a vector or matrix.
b	Specifies a diagonal of a. b is an integer.

Name	Description
c	Returns a diagonal matrix or the diagonal of a matrix. c is a vector or matrix. If a is a matrix, diag(a) returns a column vector containing the diagonal of a and diag(a, b) returns a column vector containing the bth diagonal of a. If a is a vector of length n, diag(a, b) is a square matrix of size n+abs(b) with a bth diagonal determined by a.

A = [1, 0, 0; 0, 2, 0; 0, 0, 3]
C = diag(A)
