What is your question? When you want somebody to do your work, offering money is a standard method.

Sobel filter does not do sharpening! You can tell that because the central element of the kernel is zero which means that nothing is added to the original image. It's purely an edge detector, not a high frequency boosting filter. You will not see your original image with enhanced/sharpened edges.

Hint:
edgeImage = conv2(imageArray, sobelKernel, 'same');
You can find the Sobel kernels anywhere online.
