| DoubleComplexUpperTriMatrix Class |
Class DoubleComplexComplexUpperTriMatrix represents an upper triangular matrix of double-precision
complex numbers. An upper triangular matrix is a square matrix with all elements
below the main diagonal equal to zero.

The DoubleComplexUpperTriMatrix type exposes the following members.
Constructors Properties | Name | Description |
---|
| Cols |
Gets the number of columns in the matrix.
|
| DataVector |
Gets the data vector referenced by this matrix.
|
| Item |
Gets and sets the value at the specified position. Zero matrix elements
are not stored, so assigning a non-zero value to a matrix element
above the diagonal of the matrix raises an exception.
|
| Order |
Gets the order of the matrix.
|
| Rows |
Gets the number of rows in the matrix.

TopRemarks
The matrix is stored in a vector column by column. For efficiency, zero elements are not stored.
For example, the following 5 by 5 upper triangular matrix:
| a00 a01 a02 a03 a04 |
| 0 a11 a12 a13 a14 |
A = | 0 0 a22 a23 a24 |
| 0 0 0 a33 a34 |
| 0 0 0 0 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].
