How can I save multiple figures plotted in double y-axis graphics in seperate folders?

My matlab code for plotyy axis starts as below:

figure;[haxes,hline1,hline2] = plotyy(dat_s,M1_T,dat_s,T);

For one y-axis we use fullfile command, I have asked in my previous question and I have got this answer. But for double yy axis how can I save figures as fig. file and jpg. file in separate folders?

For example;

X.fig and X.jpg in A folder.

and

Y.fig and Y.jpg in B folder.

Thanks a lot..

What point, precisely? SAVEAS can save the figure in one of a dozen or more ways; you simply call it with the desired format string specifically or you can use one of the predefined extension strings when creating the filename and then it will automagically use that to determine the figure type to match. You simply have to choose one way or t'other (or ensure you write code that creates a file and option that match or you can end up with mismatched filenames and types in the associated file). See the doc for details on what are the file types known and assumed extensions that go with them.

Again, how you create a subdirectory structure for the filename is totally independent of the manner in which the data are saved; use fullfile and the other string-handling functions specifically for creating and handling file names for that purpose; only that you must have a fully-qualified filename to ensure you're putting the files where you really intend; otherwise a partially-qualified name or a filename without any directory information will be relative to the location where the function is executed.

Also note that using gcf has some potential for error; if there's any possibility at all that the focus can be shifted by the user from the time the figure is created before it is saved, then you'll get the figure the user has last pointed to, NOT necessarily the one you're intending; hence the recommendation to save the handle to the figure you intend when you create it so you can refer to the desired one unequivocally.

Sounds like a plan.. :)

The point is, don't mix up what are really independent parts of the problem; naming the file and where you store it are one issue, how you store the data inside it is another.

Granted, one wants an extension to match the content, but ML will take care of that for you automatically unless you want something other than a default value (which is not, generally, a wise thing).
