You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: simplenn_caffe_deploy.m
    path of file: ./repos/refinenet/libs/matconvnet/utils
    
    the code of the file until where you have to start completion: function simplenn_caffe_deploy(net, caffeModelBaseName, varargin)
% SIMPLENN_CAFFE_DEPLOY export a simplenn network to Caffe model
%   SIMPLENN_CAFFE_DEPLOY(NET, CAFFE_BASE_MODELNAME)
%   Export a simplenn network NET to a Caffe model.
%   The caffe model is stored in the following files:
%
%     [CAFFE_BASE_MODELNAME '.prototxt']   - Network definition file
%     [CAFFE_BASE_MODELNAME '.caffemodel'] - Binary Caffe model
%     [CAFFE_BASE_MODELNAME '_mean_image.binaryproto'] (optional) -
%         The average image (if set in net.normalization.averageImage)
%
%   Compiled MatCaffe (usually located in `<caffe_dir>/matlab`, built
%   with the `matcaffe`
