# ScalarProduct Method

Overload List

| Name | Description
--- | --- | ---
| 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.
