Hi everyone,

did you get lost on the intuition of linear transformation?

I found it very confusing about a matrix multiply a matrix

thanks for your help

hey there, thanks for asking. In the lecture we learned about how to add, multiply matrices with same number of row and columns. I am just curious when the number of rows and columns are different then how the operation will be different. Going down that rabbit hole to figure out is quite confusing and I have not found an intuitive way to understand.

Another thing is Numpy’s representation of a matrix is a new thing to learn, like how it treats a vector in 1D, 2D, 3D [1,2,3], [[1,2,3]] , [[[1,2,3]]]

that’s why
