Both ITensor and IQTensor now support the following element access methods, where I1, I2, ... are Index objects (or IQIndex objects in the case of IQTensor): T.set(I1(n1),I2(n2),..., x); //x is a Real or Cplx scalar T.real(I1(n1),I2(n2),...) //returns x, assuming x is real, throws if x is complex T.cplx(I1(n1),I2(n2),...) //returns x as a complex number
