Undefined function 'feautre_vec' for input arguments of type 'char'.

I wrote a MATLAB code which consists of two function files. The problem is that once I try the code

I get the following error: "Undefined function or method 'time' for input arguments of type 'char'"

I don't understand what I did wrong.

I will appreciate your help.

You need to be calling feature_vec with the content of an image. The image needs to be 2 dimensional (note that .jpg files are always 3 dimensional). I am not certain if the code will act correctly if the image passed is uint8; it might have to be double.

The two functions need to be somewhere on your MATLAB path.
