Gets the outer product (matrix product) between two vectors (a*bT).

Namespace:  Accord.Math
Assembly:  Accord.Math (in Accord.Math.dll) Version: 3.8.0
Syntax
```public static int[,] Outer(
this short[] a,
double[] b,
int[,] result
)```

#### Parameters

a
Type: SystemInt16
b
Type: SystemDouble
result
Type: SystemInt32

Type: Int32

#### Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type . When you use instance method syntax to call this method, omit the first parameter. For more information, see Extension Methods (Visual Basic) or Extension Methods (C# Programming Guide).
Remarks
In linear algebra, the outer product typically refers to the tensor product of two vectors. The result of applying the outer product to a pair of vectors is a matrix. The name contrasts with the inner product, which takes as input a pair of vectors and produces a scalar.
