##
## Return the number of rows and columns of @var{A}.
##
## With one input argument and one output argument, the result is returned in a
## row vector. If there are multiple output arguments, the number of rows is
## assigned to the first, and the number of columns to the second, etc.
##
## If given a second argument, @code{size} will return the size of the
## corresponding dimension.
