The discussion revolves around taking the derivative of a transposed matrix expression involving a matrix \( z \) and a column vector of ones. Participants are trying to clarify the dimensions and definitions of the matrices involved.
Some participants have provided insights into the dimensionality of the matrices, leading to a reconsideration of the original expression. There is an acknowledgment of the need for clarity regarding the definitions of \( z \) and the column vector of ones.
There is uncertainty regarding the dimensions of the matrices involved, which affects the interpretation of the derivative operation. Participants are navigating the implications of these assumptions on the problem at hand.
MaxManus said:I have a matrix (z-m1) ^T where z is a matrix and 1 i a column where all the elements are 1. Can anyone help me with taking the derivative with respect to m?
T is for transpose.
