Detailed Description

Class representing matricies with 3 rows, and 3 columns.

CSIBCMatrix33d objects represent matricies, and define a set of operations which are useful in the context of a matrix. Unlike CSIBCMatrix4x4, there is no method of accessing the matrix data directly, thus it does not matter whether the values are stored in column major, or row major order.

This class uses double precision floating point numbers to store element values. There exists three other matrix classes, CSIBCMatrix44d, CSIBCMatrix4x4 and CSIBCMatrixMNd. They are used to represent 4x4 matricies with double precision floating-point numbers, 4x4 matricies with single precision floating-point numbers, and MxN matricies with double precision floating-point numbers, respectively.
