o Block()

Method Index

o o(Zmat, int[], int[])
This method takes a Zmat A and two arrays ii and jj of length m and n and produces an (m-1)x(n-1) block matrix Zmat[m-1][n-1], whose (i,j)-element is A.get(ii[i], ii[i+1]-1, jj[j], jj[j+1]-1).

This method takes a Zmat A and two arrays ii and jj of length m and n and produces an (m-1)x(n-1) block matrix Zmat[m-1][n-1], whose (i,j)-element is A.get(ii[i], ii[i+1]-1, jj[j], jj[j+1]-1). Throws a JampackException if

Parameters:
A - The matrix to be partitioned
ii[] - The row indices of the partition
jj[] - The column indices of the partition
Returns:
The block Zmat
Throws: JampackException
Thrown if the submatrices are not conformable.
