Lecture 20: Introduction to Color Science (Cont) (39)

I'm confused by the dimensions of the matrix. The slide makes it seem that M_sml is a tall matrix while M_rgb is a wide matrix and their product should be a NxN matrix. Are the dimensions written in col x row format?

Yeah they must just be written backwards, since otherwise you wouldn't be able to multiply Nx3 and 1xN matrices

I think they just denote the dimensionality of a matrix by #cols x #rows.

I was confused about this as well, best to re-write this as (row, col) for cheatsheet. I tried reversing the multiplication order but thats even more confusing. Thanks @GitMerlin
