HankelMatrix

HankelMatrix[n]

gives the n×n Hankel matrix with first row and first column being successive integers.

HankelMatrix[{c1,c2,,cn}]

gives the Hankel matrix whose first column consists of elements c1, c2, .

HankelMatrix[{c1,c2,,cm},{r1,r2,, rn}]

gives the Hankel matrix with elements ci down the first column, and ri across the last row.

Details

  • The element cm must be the same as r1. »
