|
Plus(Expression, Double) | Create an expression for augend + addend. This is equivalent to augend.Plus(addend) and is only provided for completeness. |
|
Pow(Double, Expression) | Create an expression for base ^ exp. Note that adding the result of pow to your model in any way will turn the model into a non-linear model. In order to square a variable or linear expression, use one of Square, Square, or Square. They all create linear or quadratic expressions. |
|
Pow(Expression, Expression) | Create an expression for base ^ exp. Note that adding the result of pow to your model in any way will turn the model into a non-linear model. In order to square a variable or linear expression, use one of Square, Square, or Square. They all create linear or quadratic expressions. |
|
Pow(Expression, Double) | Create an expression for base ^ exp. Note that adding the result of pow to your model in any way will turn the model into a non-linear model. In order to square a variable or linear expression, use one of Square, Square, or Square. They all create linear or quadratic expressions. |
|
Prod | Create an expression for Prod(value, ...). |
|
ScalarProduct(IEnumerableVariable, IEnumerableDouble) | Compute the scalar product between a vector of variables and a vector of coefficients. Both vectors are specified as streams of elements. |
|
ScalarProduct(IEnumerableVariable, IEnumerableVariable, IEnumerableDouble) | Compute the elementwise product between two vectors of variables and a vector of coefficients. All vectors are specified as streams of elements. |
|
ScalarProductK(IDictionaryK, Variable, IDictionaryK, Double) | Compute the scalar product between a map of variables and a map of coefficients. The function assumes that variables and coefs have the same Keys (missing keys in coefs are treated as zero) and creates a new linear expression by iterating over the keys in variables and adding up the variable/coefficient pair for each key. |
