Examples of cc.redberry.core.tensor.Fraction

cc.redberry.core.tensor.Fraction
This class describes fraction object. Numerator of the fraction can be tensor of any type, without restrictions, but denominator must be a scalar (but not necessary symbol), and constructor throws exception in other case. Fraction returns numerator indices as its indices. Returns @see Tensor @author Dmitry Bolotin @author Stanislav Poslavsky
