HANKEL(Number)

• $Number$ is the order of the hankel matrix.

Description

• This function gives the matrix with the property of hankel matrix with the given order.
• A hankel matrix is a square matrix with constant skew diagonals.
• If the i,j element of Hankel matrix A is denoted $A_{i,j}$, then we have

• A hankel matrix is also called as catalecticant matrix.
• Here HANKEL(3) 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.
• Sometimes this type of matrices are also called as orthosymmetric matrices.
