The metatable for a 2x2 matrix class, use the new function to actually create an object.

We also inherit all the functions from tardis.array

m2 = m2:adjugate()
m2 = m2:adjugate(r)

Adjugate this m2.

If r is provided then the result is written into r and returned otherwise m2 is modified and returned.

m2 = m2:cofactor()
m2 = m2:cofactor(r)

Cofactor this m2.

If r is provided then the result is written into r and returned otherwise m2 is modified and returned.

value = m2:determinant()

Return the determinant value of this m2.

m2 = m2:identity()

Set this m2 to the identity matrix.

m2 = m2:inverse()
m2 = m2:inverse(r)

Inverse this m2.

If r is provided then the result is written into r and returned otherwise m2 is modified and returned.

value = m2:minor_xy()

Return the minor_xy value of this m2.

m2 = tardis.m2.new()

Create a new m2 and optionally set it to the given values, m2 methods usually return the input m2 for easy function chaining.

m2 = m2:scale(s)
m2 = m2:scale(s,r)

Scale this m2 by s.

If r is provided then the result is written into r and returned otherwise m2 is modified and returned.

m2 = m2:transpose()
m2 = m2:transpose(r)

Transpose this m2.

If r is provided then the result is written into r and returned otherwise m2 is modified and returned.
