Hello,
Please help me with the following:
I have a matrix M 150x4.
Ι need to calculate the distances (separately, the Euclidean and Cityblock) between the 1st element M(1,1) and all the others of M.
Also, I need to plot these distances.
Thank you very much.
Best,
Pavlos

What have you tried already? It is more useful for you to have your code improved than someone else doing your homework.
What defines the distance between element? And how do you want to plot the distance? Just as a 3D point cloud?

If you have the statistics toolbox you can use pdist2
m=[1 1 1 1;2 2 2 2;3 3 3 3;4 4 4 4;5 5 5 5]
dist1=pdist2(m(1,:),m,'euclidean')
dist2=pdist2(m(1,:),m,'cityblock')
%plot index vs distance
plot(1:length(c),[dist1;dist2])
