# 4x4 Matrix

The 4×4 Matrix features the same methods of accessing its variables as the 2x2 Matrix; but of course, has an extra column and row.

In addition to the base identity and custom matrix constructors, the 4×4 matrix also has constructors for:

• A 4×4 rotation matrix constructed by means of a rotation vector and the angle in degrees.
• A 4×4 scale matrix, taking a Vector3.
• A 4×4 matrix with translation in the x, y, and z directions as floats.
• A 4×4 projection matrix, taking `FOV`, `aspect ratio`, `near` and `far` as floats.
• A 4×4 orthographic projection matrix, taking `left`, `right`, `bottom`, `top`, `near`, `far` as floats

The 4×4 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.
• `Transform`, with scale, rotation in Euler angles, and translation as Vector3 objects.
• `Transform`, with scale, rotation in axis Vector + angles as float, and translation.
• `LookAt`, which takes position, target, and up as Vector3 objects.
• `SetScale`, which takes a Vector3 or floats
• `SetTranslation`, which takes a Vector3 or floats

As part of the `ImpulsePhysics::Matrices` namespace, you also get access to these utility functions:

• `Minor`
• `Cofactor`
