  • What does it really mean to take the inverse of a matrix?
    Note: I am talking about the left inverse of a matrix throughout this video. That is, what operation can I do to UNDO the operation I just did? For square matrices, the left inverse is the same as the inverse but for rectangular matrices, they are not the same concept.

    Very intuitive. The last part was a bit brief, may be due to time contrain. Using real life example in the first part makes this head and shoulder above other clips. Thank you.

    Absolute shame how few viewers you get, it is an absolute joke. You deserve much much more. I hope you continue making videos, are you able to make a living from these or is this more of a hobby project?

      Because the better videos are newer and there aren’t that many. But probably the best channel around intuition wise.

    finally a GOOD lesson about the need of the inverse of a matrix ! very good explanation ! for years am waiting for such a lesson. mathematics are coming from the real life. this is how mathematics should be teach in school ! great job ! thank you !👏

    Love your videos. Hope you can do more matrix algebra starting from the basics

    Love the way you project the vector space to that easy-to-understand area graph. Very intuitive. But would like to know more why R^3 to R^2 would means 2X3 matrix

    Can you talk about the Fourier transform and the fast Fourier transform? It has a lot of relevance to data science and is good for knowing a bit more about linear algebra

    Hey, thanks for the great video!
    I think it would be interesting and helpful to know how the pseudo inverse of a matrix (which is defined even for non-square matrices) fits into the whole picture.

    You just waste our time with this useless explanation about the Matrix inversion with no description of how to do it ...
