vl_nnconv appears to be a function from the 3rd party MatConvNet. You'll need to download and install that toolbox.

Installing matconvnet depends on whether you wanna use GPU or no. if you do not have gpu the steps are very easy. Step 1: download the package from their website http://www.vlfeat.org/matconvnet/download/matconvnet-1.0-beta18.tar.gz

Step 2: uncompress the file at your local disk.

Step 3: if you want you can compile the package. - cd MatConvNet - addpath matlab - vl_compilenn

Step 4: is the setup: - run MatConvNet/matlab/vl_setupnn

that set. see this link: http://www.vlfeat.org/matconvnet/install/
