Found problem with opening MATLAB and possible solution https://www.mathworks.com/matlabcentral/answers/96260-why-do-i-receive-the-error-undefined-function-or-variable-usejava-when-trying-to-start-matlab-6 but did not have time to try it.

In order to open pathdef.m, I used my admin privileges to change permissions so that everyone can read and execute this file.

Note 04/05

Got Matlab working by changing the privileges above. I had to also give everyone the right to modify pathdef before Matlab accepted it. When opening Matlab, there are a bunch of files that we don't have permission to run because they are in Amir's user folder but they do not seem important to the Entrep code so I am ignoring this for now.

I had issues running the code because the various paths and m folder references in the code do not match our own path variable, so I took an easy route and copied all of the provided files into one big folder called Adjusted Code in the same folder as Original Code. Now, I can actually run the files but they take forever.

I planned on stopping the code at about 30 minutes of runtime, but right then, something mysteriously printed so I decided to let it keep going. Since I don't totally understand what this code is doing, I'll let it run until I come back on Friday and hope I get some output that provides insight into what is going on.

In the meantime, I downloaded Atom and set it up so that I can write julia code in Atom and run it in the terminal. I am reviewing Julia syntax concepts for when I finally start to code.

Note 04/12

I went through to fix the permission denied error that displays at the beginning of every time one opens Matlab. First, I used admin privildeges to let myself into Amir's account, then copy and pasted all the folders that he had added to the pathdef.m file. Then I copied them into E:/McNair/Software/Scripts/MatlabFolders. Then, I took myself off the permissions for Amir's folders. Next, I changed all of the path definitions that had lead to Amir's folder to start with this new path. Now, the permission denied error does not show up. Matlab Usage Julia Usage

Notes 6/28/17

The following is for MonteData -> MSM -> Genetic Algorithm

  Figured out that the value "W" in msmf_corr_coeff.m is an empty vector. 

  When it is multiplied by mm-M0 (which always happens to be 0), it returns an empty vector 

  This is why the error suggests the fitness function must return a scalar value 

  When I assign W =6 for example, the program runs just fine. 

  I need to figure out what W does and how it is assigned in order to fix this issue.
