Derivative of 2x2 matrix

WebNov 25, 2016 · In the 2 × 2 case notice that f (i.e. the matrix ( a c b d)) maps the 4 vertices of the unit square -- ( 0, 0), ( 1, 0), ( 1, 1), ( 0, 1) -- to the new points ( 0, 0), ( a, b), ( a + c, b + d), ( c, d). You can confirm for yourself that the area of the quadrilateral with these new vertices is a d − b c. For Further Reference: WebIn the 2 × 2 case: If M is your matrix, then it represents a linear f: R n → R n, thus when you do M ( T) by row times column multiplication you obtain a vectorial expression for your f ( T). Thus ∂ M ∂ T is just the derivative of the vector M T, which you do component-wise.
