| FloatLowerTriMatrix Class |
Class FloatLowerTriMatrix represents a lower triangular matrix of single-precision
floating point values. A lower triangular matrix is a square matrix with all elements
above the main diagonal equal to zero.

The FloatLowerTriMatrix 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 row by row. For efficiency, zero elements are not stored.
For example, the following 5 by 5 lower triangular matrix:
| a00 0 0 0 0 |
| a10 a11 0 0 0 |
A = | a20 a21 a22 0 0 |
| a30 a31 a32 a33 0 |
| a40 a41 a42 a43 a44 |
is stored in a data vector v as:
v = [a00 a10 a11 a20 a21 a22 a30 a31 a32 a33 a40 a41 a42 a43 a44 ]
In general,
A[i,j] = v[i(i+1)/2 + j].
