====== 3x3 Matrix ======

The 3x3 Matrix features the same methods of accessing its variables as the [[2x2_matrix|2x2 Matrix]]; but of course, has an extra column and row.

In addition to the base identity and custom matrix constructors, the 3x3 matrix also has constructors for:
  * A 3x3 rotation matrix constructed by means of a rotation vector and the angle in degrees.
  * A 3x3 rotation matrix constructed with ''pitch, yaw and roll'' in degrees.

The 3x3 Matrix also features additional functions in its class. Here is the complete list:
  * ''Transpose''
  * ''Determinant''
  * ''Inverse''
  * ''Adjugate''
  * ''RotateX'', ''RotateY'' and ''RotateZ'', all of which rotate the matrix by the given angle around their respective axis as the name dictates.
  * ''RotateAxis'', which rotates this matrix for the given angle around the given axis.
  * ''Rotate'', which takes ''pitch, yaw, and roll'' in degrees.

As part of the ''ImpulsePhysics::Matrices'' namespace, you also get access to these utility functions:
  * ''Cut3x3'', which 'cuts' a matrix out of a [[4x4_matrix|4x4 matrix]]
  * ''Minor''
  * ''Cofactor''
