generate a matrix along the length of an inclined line

I have an inclined line of a given length 'L' in XY coordinate plane, at a certain angle alpha with global X axis.My input would be a certain length say 's' and I want to generate a matrix which contains X and Y coordinates along the line at a distance 's' that I have inputted. So, basically the coordinates are at a spacing of 's' along the line of length 'L'. How can i get that matrix?

I hope I got your question right. I suppose you have a line originating at (x0/y0) with an angle alpha and a length L:

 L=5;alpha=pi/6;
 x0=2;y0=1;
 figure, hold all
 plot([x0 x0+L*cos(alpha)],[y0 y0+L*sin(alpha)])
 axis equal

Secondly, you have a distance s smaller than L and you want all steps of size s on that original line, right?

 s=.5;
 xs=x0+(0:s:L)*cos(alpha);
 ys=y0+(0:s:L)*sin(alpha);
 plot(xs,ys,'o')

If you don't want (x0/y0) to be part of (xs/ys), just increment starting from s instead of starting from 0.
