Undefined function 'caffe_' for input arguments of type 'char'

[HBR]

Hi all. I am trying to run the classification_demo. I have completed the steps stated at https://github.com/BVLC/caffe/tree/windows. I only have Matlab enabled to true. My code is extremely simple

im = imread('cat.jpg');
[score, class] = classification_demo(im, 0);

But when I run it I get the following error. Undefined function 'caffe_' for input arguments of type 'char'

Can anyone help me on this ?
