How to write a program for finding the ortogonal projection of a given vector V1 on another given vector V2??
How should ı do? Which Matlab commands should i use?

V1 .* V2 is the elementwise multiplication. You want the dot product instead: V1 * V2.' or dot(V1, V2). Mathematically this can be expressed as sum(V1 .* V2) also.
V1 .^ 2 squares each element, but you want the norm of the vectors: norm(V2)^2. This can be written as sum(V1 .* V1) also.
Try it. There are some different possible commands only, so you can solve this by "gunshot programming": modify the code until the result is as expected.

V1 = input('Vector V1= ');
V2 = input('Vector V2= ');
frstprt= dot(V1,V2)/norm(V1,2)^2;
scndprt = frstprt.*V1;
I got the correct result with this Matlab program.Thank you very much for helping me understand the matlab code.
