Examples
// create a vector v = Vec("x",5) // create an empty set S = Set() // create a matrix with diagonal v M = Diag(v) // number of elements in v, S, and M elems(v) elems(S) elems(M) |  |  |
number of elements of a symbolic object
n = elems( s )
symbolic
non-negative integer
Returns the number of elements n of a symbolic object s.
