Bro I don't know how to calculate 6×3 and 3×6 matrix but you do that directly and how can we understand broooo ...any way thanks ..🙃

[@Mallesh.prabha.]

Yes I donot understand how to calculate it

[@SublineYT]

​@@Mallesh.prabha. It's the same method as normal matrix multiplication, if you have a calculator you can do it a lot easier

In order to multiply matrix to find K ,we have to follow order that is [B]'[D][B] not [B'][B][D] .order is important.Clear this doubt

Sir, here for finding k matrix, instead of multiplying B with B transpose you multiplied B transpose with D matrix first. 》》B^T D B My doubt is if we first multiply B with B transpose and then multiply the matrix with D 》》B^T B D ....will it change the answer Sir? @ 20:22

[@the_candid_mechanic]

The video was really helpful Sir. Thanks a lot Sir.

[@rizqyagung7319]

B^T D B is quadratic of form in terms of matrix, it will explain more details in advance mathematics. In example while calculating kinetic energy in terms of matrix, we will use v^T M v instead of v^T v M. Then, if u use the B^T B D form, u will find different result. Furthermore, u can check that B^T B D form will result different size of matrix against the B^T D B form. thanks
