can anyone one here 're-teach' me abt matrix and it's basic operations? i have learnt in sec. skl but throw everything back to skl lo..but i want to re-learn it to do something..thanks in advance..
a b + w x = a + w b + x
c d y z c + y d + z
same for subtraction
a b * w x = aw+by ax+bz
c d y z cw+dy cx+dz
determinant :
( a b
c d ) Det (M) = ad -bc
Inverse: = 1/(ad-bc) ( d -b
-c a)
3 x 3 onwards require alot more calculation...
then what abt the transformation one?
