Creates the array representation of a 4x4 matrix. The use of the array directly eliminates any overhead associated with the class representation defined above. The returned matrix is cleared to all zeros.

Creates a 4x4 matrix initialized from the given array.

Creates the array representation of a 4x4 matrix. The use of the array directly eliminates any overhead associated with the class representation defined above. The returned matrix is initialized with the identity

Computes the determinant of the matrix.

Returns true if the components of mat0 are equal to the components of mat1.

Constructs a rotation matrix from its Euler angles using the ZXZ convention. Given the euler angles [theta1, theta2, theta3], the rotation is defined as rotation = rotation_z(theta1) * rotation_x(theta2) * rotation_z(theta3), where rotation_x(theta) means rotation around the X axis of theta radians.
