I1 = imread('gantrycrane.png');
I2=im2double(I1);
[hog1, visualization] = extractHOGFeatures(I2,'CellSize',[32 32]);
subplot(1,2,1);
imshow(I2);
subplot(1,2,2);
plot(visualization);
??? Undefined function or method 'extractHOGFeatures' for input arguments of type 'double'.

Type ver to see if you have the Computer Vision System Toolbox - I'm not sure it existed yet in that R2011a version. Otherwise, this is a good excuse to upgrade your 4 year old version to the latest version.

I don't have that toolbox. Is extractHOGFeatures a built in function or some custom function someone gave you? Try this:
which -all extractHOGFeatures
What does it say?

extractHOGFeatures was introduced in R2013b.

Why would it be? It's not even there in the R2011a version that you have. Like Dima said, that function was introduced in R2013b, even though you may have an earlier version of the toolbox. So you don't have it.
