	`x`	n x p x d1 x d2 x ... x dn array
	`d`	n x p x d1 x d2 x ... x dn array or scalar
Output:
	`z`	n x p x d1 x d2 x ... x dn array

Note:

For elements xij < 0 zeros are returned. Take numerical exactness into account !

Example:

a=#(0.5, 0.4)~#(0.01, 1)~#(-1,2) cdfc(a, 6) setenv("outputformat","%8.5f") cdfc(a, 6) setenv("outputformat","%8.5lg")
