There is no direct way, but you can use 'IMDILATE' to dilate the pixels. For instance, you can use the following commands:

%Using imdilate
>> se = strel('line',11,90);
>> img = imdilate(rgb1,se); %rgb1 is the matrix
>> imshow(img) %save the figure as png file
>> saveas(gcf,'myfile.png')

Also, note that the above functions require Image Processing Toolbox.For more information, refer to the following documentation link:
