There is no matrix in Julia that satisfies the constraint that one column is
all integers, another column is all integers and the last is all floats,
because all matrices in Julia have a homogeneous type.
There are several possible solutions:
(1) Use Array{Any} and then enforce your constaints by hand.
(2) Use Array{Vector} and store the columns as the entries of an array of
columsn.
(3) Allow all columns to be floats.
