Z_i,j
There are many special cases for calculating the i,j
th term in Z
.
These special cases must be handled on a term-by term basis.
This function handles all those cases.
See Z_byname()
for details.
The X
matrices must be same size, must have same row and column names, and
must have same row and column types.
Note that i
and j
must be positive and less than or equal to
nrow(X)
and ncol(X)
, respectively.
