How to project given vectors in matlab

v1 = [1.12;2.10;7.03;4.15;6.13] v2 = [1;-1.01;1.02;-1.03;1.04]

I need to calculate projection of v1 onto v2 how would I code this into matlab?

A dot product.

help dot

You will need the norm of the vector v1.

help norm

E.g., see this link

https://en.wikipedia.org/wiki/Vector_projection

u = v2/norm(v2);
result = dot(v1,u)*u;
