HANKEL
MATRIX("HANKEL",order)
- is the order of the hankel matrix.
is the order of the hankel matrix.Description
- This function gives the matrix with the property of hankel matrix.
- A hankel matrix is a square matrix with constant skew diagonals.
- If the i,j element of Hankel matrix A is denoted , then we have
, then we have.
.
- i.e., The form of Hankel matrix is:
.
.
- A hankel matrix is also called as catalecticant matrix.
- Here MATRIX("hankel") is gives the hankel matrix of order 3 with decimal values.
- A Hankel matrix is an upside-down Toeplitz matrix.
- A matrix whose entries along a parallel to the main anti-diagonal are equal, for each parallel.
- Equivalently, is a Hankel matrix if and only if there exists a sequence, such that ,If are square matrices, then is referred to as a block Hankel matrix.
