"TS.Global" I got this as a part of a matlab code. Can anyone help to understand what does mean? I have seen this dot operator as a part of structure; is this mean the same?

The dot operator such as TS.Global can mean:
  • That TS is a struct(), and Global is a field in the struct
  • That TS is an object, and Global is a property of the object. It is not necessarily an object created in MATLAB: it might be an object created in Java for example
  • That TS is an object, and Global is a method associated with the object. It is not necessarily an object created in MATLAB; it might be an object created in Java for example
  • That TS is a package created with a +TS directory and Global is a function defined in the package; https://www.mathworks.com/help/matlab/matlab_oop/scoping-classes-with-packages.html
TS.Global appears to be used in the Model Based Calibration toolbox. When I chase back the source of TS from old mbcmodels/@xregoptmgr source code that I find online, then it appears that the variable TS is a "model", probably of class mbcmodels or a subclass of that.
Possibly these days the Global property corresponds to https://www.mathworks.com/help/mbc/mbccommandline/global.html

But you should have already had that file if you had the stats toolbox installed.
  1. Did you not have the stats toolbox installed and had to buy it?
  2. Or did you have your own version of mle.m that it was using instead of the toolbox version?

TS is probably either a class or a structure. Global could be a field of the TS structure. Or if TS is a static class, Global could be a method of the static class. Or if TS is an instance of some class (with a different name) then Global could be a method or the class or a property of the class.
But why didn't you answer Walter's question when he asked you to put this in your code and tell us what it says:
class(TS)
