Suppose I have the following
function [G,Tstat,P] = Fama_MacBeth(X,Y)
% Inputs:
% X is the matrix of explenatory variables of dimensions TxNxK, where T is
% the sample size, N is the number of assets, and k is the number of
% independent variables;
% Y is the matrix of excess returns of dimensions TxN;
Now I have my data Y of size T x N and X of size T x N.
I know that k = 3. However , how do I transform my matrix X such that it becomes T x N x 3

%random example
y = reshape(1:30,5,6);
repmat(y,1,1,3)
ans =
ans(:,:,1) = 1 6 11 16 21 26 2 7 12 17 22 27 3 8 13 18 23 28 4 9 14 19 24 29 5 10 15 20 25 30 ans(:,:,2) = 1 6 11 16 21 26 2 7 12 17 22 27 3 8 13 18 23 28 4 9 14 19 24 29 5 10 15 20 25 30 ans(:,:,3) = 1 6 11 16 21 26 2 7 12 17 22 27 3 8 13 18 23 28 4 9 14 19 24 29 5 10 15 20 25 30
