Matrix of size 100*100- Meghna

[Meghna Karkera]

Dear Respected Sir

I am Meghna, a PhD student. I have installed python in my ubuntu OS from
your website recently and tried using spyder and jupyter.

May I request you to help me with importing few matrices, each of size
100*100 in python from XLSX and perform operations on the matrices like
addition, multiplication, finding matrix inverse, creating diagonal
matrices each of size 100*100 from column vectors each of size 100*1,
creating identity matrix of size 100*100. I have surfed in the internet,
but unable to get answer for it.

I would be grateful to you if you could help me in this regard.

Thanking you

Sincerely
