Given a 2D image I had to create a vector of features for each pixel (i,j). To do that, I created a 3D matrix such that the 3rd dimension is a vector of features for the pixel. For example, (2, 3, :) represents the vector of features for pixel (2,3) in the image .
Now I need to convert this 3D matrix into 2D matrix where each row is a vector of features. I tried to understand the function reshape() but could not get it to work the way I need.
I would appreciate some expert advice
Thank you

feat = reshape(x,size(x,1)*size(x,2),size(x,3))
