  • You need to demonstrate more effort than this. This isn't a place to get people to write code for you. – Zane Apr 18 '14 at 15:51

img = imread('your_image.png' , 'png');  //extension can be jpg,png,...

img = im2double(img);   // convert uint8 to double

img_large = interp2(img, 'linear');   //bilinear interpolation

figure; imshow(img_large,[]);    //see your enlarged image

hope it helps
