Hi Everyone,
I'm having difficulties with 'saveas' function. This is the only output format I can find:
saveas(H,'FILENAME','FORMAT')
I am looking for an example output format for this function for how to add a changing file name (for each for loop iteration) and how to add location (where I want the files to be saved).
My question:
I have the following command (taken from an inside of a for loop):
hist_pat=figure
histogram(log_band_power) %matrix of 114x5 data
title(strcat('logged-data '+ currentSubject + ' parc60')); %plot title changes with each loop; different patient
saveas(hist_pat, '') % hist_pat is the plot I want to save, '' is for the name of the plot; the problem
...where should I add the following to the [saveas (hist_pat, '')] line of code:
changing name and location: (strcat(dataLoc, 'log_check/log_histogram', currentSubject, 'log.svg'),'hist_pat')
I know the layout will be differnet of the line above, but I can't find any examples online on how to structure that line of code.
Any suggestions?
Thank You!

I think I can answer my own question now!
If anyone is interested:
saveas(gca,string(strcat(dataLoc, 'log_check_patient_60/log_histogram/', currentSubject, '.fig')));
dataLoc: the 'root' path of the location where to save th figure
'log_check_patient_60/log_histogram/': the name of the folder (further location specifications, where I want the file to be saved)
currentSubject: the name of the file, which will change with each for loop in my code
'.fig': specification of the figure, can also use .svg for example

Rather than squeezing everything onto one line, using two lines makes the code intent much clearer:
fnm = strcat(dataLoc, 'log_check_patient_60/log_histogram/', currentSubject, '.fig')
saveas(gca,fnm);
You should also learn about SPRINTF and FULLFILE.

Thank you @Adam Danz & @Stephen23!
I will have a look at SPRINTF and FULLFILE, haven't come across those yet.
Thats a great suggestion @Stephen23, I'll add that to my code.
