computer vision - Is 'Digit Classification Using HOG Features' matlab example only available in the 2014 version? -

i utilize r2013a version of matlab. tried follow path,

syntheticdir = fullfile(toolboxdir('vision'), 'visiondemos','digits','synthetic'); handwrittendir = fullfile(toolboxdir('vision'), 'visiondemos','digits','handwritten');

but there no files named digits.

also upon running,

trainingset = imageset(syntheticdir, 'recursive'); testset = imageset(handwrittendir, 'recursive');

i got next error : undefined function 'imageset' input arguments of type 'char' .

i'm trying effort example, http://www.mathworks.in/help/vision/examples/digit-classification-using-hog-features.html

usually consult release notes of respective toolboxes find out when new function introduced.

for digit classification example mentioned, uses imageset a new feature in r2014b, extracthogfeatures function introduced in r2013b. uses fitcecoc statistics toolbox. a new function in r2014b.

it nice if documentation provided info in easier way...
