Symbol of Operator.

(const Operator lhs - const Operator rhs) -> Operator​

Subtracts one operator from another. Returns a generic Operator for basic subtractions, ComplexOperatorSum when explicitly working with complex coefficients.

Parameters​

  • lhs: Left-hand side value.
  • rhs: The operator being subtracted (subtrahend).

Returns​

An Operator (generic) or ComplexOperatorSum representing the difference.

Example​

var diff1 = X(0) - Y(0)                   // Operator - Operator → Operator (generic)
var diff2 = 2.0*X(0) - Y(0)               // RealOperatorSum - Operator → RealOperatorSum
var diff3 = X(0) - (2+1i)*Y(1)            // Operator - ComplexOperatorSum → ComplexOperatorSum
