Parameters

factor

Type: T
The scale factor.

left

Type: Extreme.Mathematics.GenericVectorT
A VectorT.

right

Type: Extreme.Mathematics.GenericVectorT
A VectorT.

Return Value

The symmetric outer product of two vectors A and B is defined as AB^T + BA^T. Where an outer product of two vectors is in general not symmetrical, adding the transpose ensures that the result is symmetrical.

The length of left must equal the number of rows and columns of this instance.

This method uses the level 2 BLAS routine DSYR2.
