i have two points - x1,y1,z1; x2,y2,z2
i want to create a vector with many points between these two points, and that these points will all be on the same line.
how can i do that?
thanks!

x=linspace(x1,x2,N);
y=linspace(y1,y2,N);
z=linspace(z1,z2,N);

As an aside, if you want the points to be equidistant along some arbitrary curve, bending and turning all over the place, then you can use John D'Errico's interparc http://www.mathworks.com/matlabcentral/fileexchange/34874-interparc. linspace() would not work in that situation. Though for a perfectly straight line like your current situation, Matt's solution is totally accurate.
