Thread Safety

Public static (Shared in Visual Basic) members of this type are safe for multithreaded operations. Instance members are not guaranteed to be thread-safe.

Remarks

A symmetric matrix is equal to its transpose. In other words, A[i,j] = A[j,i] for all elements i,j in matrix A.
The matrix is stored in a vector column by column. For efficiency, only the upper triangle is stored. For example, the following 5 by 5 symmetric matrix:

    | a00 a01 a02 a03 a04 |
    | a10 a11 a12 a13 a14 |
A = | a20 a21 a22 a23 a24 |
    | a30 a31 a32 a33 a34 |
    | a40 a41 a42 a43 a44 |

is stored in a data vector v as:

v = [a00 a01 a11 a02 a12 a22 a03 a13 a23 a33 a04 a14 a24 a34 a44 ] 

In general, A[i,j] = v[j(j+1)/2+i], i<=j v[i(i+1)/2+j], j<i
