I edit the code in this format
I=imread('first palm.jpg'); subplot(1,2,1); imshow(I);title('first palm'); BW1=edge(I,'sobel'); BW2=edge(I,'canny'); subplot(1,2,2); imshow(BW1);title('sobel edge detector image'); figure,subplot(1,2,1);imshow(I);title('first palm'); subplot(1,2,2); imshow(BW2);title('canny edge detector image');
and this error "Error in Edges (line 4) BW1=edge(I,'sobel');" appear to me

Please format your code and explain any details about why you assume, that there is an error. E.g. a copy of the complete error message will reveal many information. Please add this by editing the question, not as comment or answer. Thanks.

You forgot to post the error, but if you use the sobel option of edge, it takes a single threshold, not an array of two thresholds like you tried to do.
