- diag:
-
- Syntax: diag ( A )
- diag ( A , K )
-
- Description:
-
- If the 1st argument is a 1xN matrix construct a diagonal
- matrix from the input . Optionally if K (scalar) is specified
- then create a matrix with the vector as the Kth diagonal.
-
- If the 1st argument is a MxN matrix, construct a 1xN matrix
- from the diagonal elements of the input matrix. Optionally if
- K is specified return the vector from the Kth diagonal of the
- input matrix.
-
- K < 0 is below the main diagonal.
- K > 0 is above the main diagonal.
