N = 12*0.5;
TAU_max = 15;
for i = 1:N
TAU(i,:) = i*(TAU_max/N);
end
I have a little loop here that creates a column vector with my dummy variables. But how I do make it so the (1,1) and (1:N) elements are 0 while still preserving my original values?

Pre-allocate TAU as a vector of zeros, then just set elements 2 through N-1:
N = 12*0.5;
TAU_max = 15;
TAU = zeros(N,1); % pre-allocate
for i = 2:N-1
TAU(i,:) = i*TAU_max/N;
end
disp(TAU);
Alternatively, set all elements and afterward set elements 1 and N to zero:
N = 12*0.5;
TAU_max = 15;
TAU = zeros(N,1);
for i = 1:N
TAU(i,:) = i*TAU_max/N;
end
TAU([1 N],:) = 0;
disp(TAU);
