If the matrix is unitary (i.e. a rotation matrix), that's the inverse
transform, but a general affine transformation is not unitary.
In the common case it's just the application of the transposed M to a
vec

Hi,
But the same question as applied to 3D world, what the difference
between 'M v' and 'v M'.
I know that 'M v' applies transformation matrix to the vector. I
understand it. And yes, I restored a little a gap in linear algebra.
But I can't understand what 'v M' will give me in 3D world.

Hi,
You are right. I fully forgot all this things. And now I'm trying to
restore the gap.

Hi, Igor.
With all due respect, looking on your questions, it seems that you have
huge knowledge gap in linear algebra.
It would be wise to firstly read how transformations can be represented by
matrices:
