I just wanted to do some simple edge detection with this code. But I get error:
"MAP must be a m x 3 array. Use im2gray for RGB and grayscale images."
I tried the im2gray function and it didn't work any better
pic = imread('good_day.jpg');
gray_pic = im2gray('good_day.jpg');
BW1 = edge(gray_pic,'Canny');
BW2 = edge(gray_pic,'Prewitt');
imshowpair(BW1,BW2,'montage');

function im2gray does not accept the jpg image, it accepts the image in pixel values
Try the following:
pic = imread('good_day.jpg');
gray_pic = im2gray(pic);
