[madhan ravi]

can you show the relevant part of the code?

Do your x and y have more than one finite point? If x and y are scalar, by default MATLAB does not provide any markers for the points.

Try

plot(x, y, 'o')

to check, if x and/or y are scalars, which plot infinitesimal small dots only.

If your code involves array division, remember to use element-wise division: ./ rather than /.
