I can't use "Detect MSER Feature"

I have the task of creating a system to read 1d barcodes. So far I followed the syntax on this link:

I found a difficulty in using the Detect MSER Feature in the section determining the region of the barcode. When I enter the code as below:

[~, cc] = detectMSERFeatures(Igray);

The output of the system is like this:

Error using detectMSERFeatures

Too many output arguments.

My question is:

1.Is there another syntax that can get a cc value?

2.Is there another syntax that can determine the region of the barcode?

Note : I'm using MATLAB R2014a, so I hope I will get an answer that matches the version of MATLAB that I am using.

Thankyou.
