Examples


## ---- initialize three distributionH objects mydist1 and mydist2
mydist1 <- new("distributionH", c(1, 2, 3), c(0, 0.4, 1))
mydist2 <- new("distributionH", c(7, 8, 10, 15), c(0, 0.2, 0.7, 1))
mydist3 <- new("distributionH", c(9, 11, 20), c(0, 0.8, 1))
## create a MatH object
MyMAT <- new("MatH", nrows = 1, ncols = 3, ListOfDist = c(mydist1, mydist2, mydist3), 1, 3)
is.registeredMH(MyMAT)
## [1] FALSE #the distributions do not share the same cdf
## Hint: check with str(MyMAT)

## register the two distributions
MATregistered <- registerMH(MyMAT)
is.registeredMH(MATregistered)
## TRUE #the distributions share the same cdf
## Hint: check with str(MATregistered)
