Such a beautiful explanation of important topics!!

The best explanation of this topic, thanks.

how translation 3*1 and rotation 3*3 is equal to 3*4

[@wahidulislam130]

a vector is represented by a single column matrix 3x1 now, think this way: a body in space will be represented by its position and orientation,. position vector is a single vector(3x1) whereas orientation vector is a combination of three vectors(3x3), thus the representation of a body in space is a combination of four(4) vectors in total. hence it will be a 3x4 matrix

[@chiragpatil6183]

we are not multiping them we are just writing them together. so, 3X1 | 3X4 gives 3X4 matrix

[@chiragpatil6183]

(3X1 | 3X3 = 3x4)*

Very important symbols you're covered. Thank you sir.

[@salmanalam9164]

oh...sorry transformation =combine of rotation and translation

[@aamirjack1832]

sir in the orientation you have written that is 3by3 matrix but that is 1by3 matrix so is that mistake or really it is like that?

[@VedanthB9]

It is a 3x3 matrix, as uXb, uYb, uZb are all 3x1 vectors. Expand them, and you will get a 3x3 matrix.

nice sir

Dude you are cool

if this is the level of teaching in IIT Kharagpur, I would rather study at my home.

What’s the problem in this? Tell me someone who can explain this better. I am all ears
