Tensor expression classes.
The TensorCwiseNullaryOp class applies a nullary operators to an expression. This is typically used to generate constants.
The TensorCwiseUnaryOp class represents an expression where a unary operator (e.g. cwiseSqrt) is applied to an expression.
The TensorCwiseBinaryOp class represents an expression where a binary operator (e.g. addition) is applied to a lhs and a rhs expression.
