Create an Empty, Prespecified LinkedMatrix Object
This function creates an empty LinkedMatrix object of a certain
size, a certain number of nodes, and certain types of nodes.
LinkedMatrix(nrow, ncol, nNodes, linkedBy, nodeInitializer, ...)
nrow |
The number of rows of the whole matrix. |
ncol |
The number of columns of the whole matrix. |
nNodes |
The number of nodes. |
linkedBy |
Whether the matrix is linked by |
nodeInitializer |
The name of a function or a function |
... |
Additional arguments passed into the |
A ColumnLinkedMatrix object if linkedBy is columns or
a RowLinkedMatrix object if linkedBy is rows.
ColumnLinkedMatrix and RowLinkedMatrix to
create ColumnLinkedMatrix and RowLinkedMatrix objects from a
list of matrix-like objects.
