I try to use fmincon with options being
options = optimset('Algorithm', 'interior-point', 'Display', 'off', 'MaxIter', 10000);
and this is the error I get:
Unrecognized function or variable 'getIpOptions'.
Error in fmincon (line 822)
options = getIpOptions(options,sizes.nVar,mEq,flags.constr,defaultopt,10,0.01);
Error in model_fitting (line 40)
[parameters_opt,ll_opt]=fmincon(@(x) RW_model(x,learning_data,false), init, [], [], [],
[], lowerBound, higherBound, [], options);
I saw that others have the same issue, but I din't find any solution.

The file getIpOptions.m should be stored in the directory identified below. Run this line of code which should open the directory where this function is stored and look for that function (for Windows)
winopen(fullfile(matlabroot,'toolbox\optim\optim'))
If the file exists, the path has somehow been removed. Restart Matlab and see if the problem goes away. If it doesn't go away, check your startup.m file (if that file exists) to determine if you're removing important paths. You could also try running restoredefaultpath.
If the file doesn't exist, is it possible that it was deleted?

Nice digging, Walter!
Here's the URL to that dissertation

That matches where I found the code... I was hoping there was a better location as the presentation of the Full Text through that link is hard to read.

Fortunately there are marginal comments for nearly every line of the code so it shouldn't be too difficult to put it into Matlab.
BTW, @Latha Maheswari S, the code starts on page 169 of the dissertation and you can search the file for the WaterFilling keyword for additional references.

[at this point the user had a copy of the Mathworks pdist2 code]
After excuting this code i get this error:
pdist2(X, Y, metric)
Unrecognized function or variable 'X'.

X = rand(23,11);
Y = rand(3,11) ;
metric = 'cosine' ;
result = pdist2(X, Y, metric) ;
