In order to save my plot, I have this excerpt of code at the end of my script. Why does this not work? From my debugging, it seems to not like the 4.2f Kn value because of its period. If I manually create str_saveas without the period, it works. Periods are valid filename characters in Windows files though. Why wouldn't Matlab permit this file naming convention? Or perhaps there's another way I should do this?
Kn=0.05;
str_saveas=sprintf('HW_4_PtA_Kn=%4.2f_FirstOrder',Kn);
saveas(figure(1),str_saveas,'fig');
Thanks, M Ridzon

The saveas() code detects the .??_FirstOrder as the file extension so it does not add .fig as an extension. It sees the 'fig' format specification so it passes the file name to saveasfig() which passes it to savefig() . But savefig() expects .fig to be present somewhere in the name.
Would it perhaps be acceptable to use
str_saveas=sprintf('HW_4_PtA_Kn=%4.2f_FirstOrder.fig',Kn);

I think the developers will simply clarify the description of 'fig' format to say more clearly that it requires .fig file extension.
