Feeding a vector to a cost function
How about CostFunction(vector(:,1), vector(:,2)) though whether this is useful depends on what you want to achieve.

Smoothing the edges of an image
If you use the edge() function, try the 'canny' option and adjust the sigma parameter to give edges as smooth as you need them.

??? Improper assignment with rectangular empty matrix.
I suspect your problem is that this line: X=x(1+(i-1)*step:seg+(i-1)); should read X=x(1+(i-1):step:seg+(i-1));
