internal.f​ininst.cds​stdsurvpro​b, inside function cdsbootstrap

I am analyzing the code of cdsbootstrap in the financial instrument toolbox(I want to adapt it to non piecewise flat hazard rates). In the last line appears the following extract of code:

[SurvProbData,HazardRates] =  internal.fininst.cdsstdsurvprob( ...
   yearfrac(Settle,ProbDates,DefProbCurveBasis),DefaultProbData,...
   yearfrac(Settle,MarketDates,Basis));

Is internal.fininst.cdsstdsurvprob accessible someway? Is it some kind of 'internal' function that I cannot modify nor see?

Yes, I think you could access this function by selecting the whole function, that is internal.fininst.cdsstdsurvprob, then right click and choose open "internal.fininst.cdsstdsurvprob" selection. Then you could check the code.

However, I don't think you can modify the code directly.

To the best of my knowledge, you could rename it and then create a file with that name under same folder. You could put your code under that file.
