You could add a laplacian to a delta function to get a new convolution kernel
laplacianKernel = [-1, -1, -1; -1, 8, -1; -1, -1, -1];
deltaFunction = [0, 0, 0; 0, 1, 0; 0, 0, 0];
scaleFactor = 1; % Whatever... From 0 to +255, including fractional numbers like 0.5
kernel = laplacianKernel + scaleFactor * deltaFunction;
% Normalize so that the mean intensity doesn't change.
kernel = kernel / sum(kernel(:))
% Filter the image
filteredImage = imfilter(originalImage, kernel);
