I have 256*256 dimension image and I want to make it 512*512 using bicubic interpolation. How to do it using csapi(x,y) or csapi(x,y,xx) function? What should be taken inplace of x & y here?

The resizing of image using bicubic interpolation method:
Example
J = imresize(I, 2, 'bicubic');%in your case
J: Resized image.
I: input image.
0.5: scaling factor

Simply use imresize():
resizedImage = imresize(originalImage, [512, 512]);
I never heard of the function csapi(). It does not show up in the help for my MATLAB.

Increasing the size will create irreularities in the image. To smoothen that out we use spline fitting.
