Increasing JVM max heap size in MAC OSX 10.12

I am running MATLAB in my MAC OSX 10.12 (16 GB of memory). I want to increase the JVM 1.8 max heap for using MATLAB without issues. The current size I have is:

 uintx MaxHeapSize    := 4294967296    {product}

To increase, I used the following command to set 8GB max memory:

$java -Xms1g -Xmx8g MATLAB_R2016b.app

but I get this error

Error: Could not find or load main class MATLAB_R2016b.app

I don't know how to solve that. I googled it but still not finding the solution. Thank you

You need to add -Xms1g -Xmx8g options in MATLAB specific file "java.opts" and recreate the app and run
