Linear Algebra Factors
This page lists the built-in methods for linear algebra operations. In these methods, you can often pass in random variables as arguments e.g. Variable<Vector> instead of Vector. For compactness, this is not shown in the syntax below.
These methods provide a convenient short alternative to using Variable<T>.Factor and passing in the factor method, as described on this page.

Inner product |
Variable.InnerProduct(Vector a, Vector b)
|
Creates a double random variable equal to the inner product of vectors a and b. |
| Matrix times vector |
Variable.MatrixTimesVector(Matrix a, Vector b) |
Creates a Vector random variable equal to product of matrix a and vector b. |
|
Matrix times matrix |
Variable.MatrixMultiply(double[,] a, double[,] b) |
Creates a double[,] random variable equal to the matrix product of ab. |
| Sum of elements |
Variable.Sum(double[] array)
Variable.Sum(IList<double> array) |
