MatDiag Method

http://www.emgu.com

Extracts a diagonal from a matrix. The method makes a new header for the specified matrix diagonal. The new matrix is represented as a single-column matrix. Similarly to Mat::row and Mat::col, this is an O(1) operation.

public Mat Diag(
	int d = 0
)

Public Function Diag ( 
	Optional d As Integer = 0
) As Mat

public:
Mat^ Diag(
	int d = 0
)

member Diag : 
        ?d : int 
(* Defaults:
        let _d = defaultArg d 0
*)
-> Mat

Parameters

d (Optional): Type: SystemInt32
Index of the diagonal, with the following values: d=0 is the main diagonal; d < 0 is a diagonal from the lower half. For example, d=-1 means the diagonal is set immediately below the main one; d > 0 is a diagonal from the upper half. For example, d=1 means the diagonal is set immediately above the main one.

Return Value

Type: Mat
A diagonal from a matrix
