Arguments

e1, e2

numeric distributed matrices or numeric vectors

Value

Returns a distributed matrix.

Details

If e1 and e2 are distributed matrices, then they must be conformable, on the same BLACS context, and have the same blocking dimension.

Examples

# NOT RUN {
# Save code in a file "demo.r" and run with 2 processors by
# > mpiexec -np 2 Rscript demo.r

library(pbdDMAT, quiet = TRUE)
init.grid()

x <- ddmatrix(1:9, 3, bldim=2)

y <- (2*x) - x^(.5)
print(y)

finalize()
# }
# NOT RUN {
# }
