Saving the plot: saveas does not seem to work

I have the following code and I try to save the plot with "saveas" but it does not seem to work. Please advise.

            x0=10;
            y0=10;
            width=375;
            height=210;
            set(gcf,'units','points','position',[x0,y0,width,height])
            set(gca,'box','on')

            % Remove tick marks from the plot

            set(gca, 'TickLength', [0 0]);

            plot(****, ****)
            hold on
            plot(****, ****)
            hold on
            plot(****, ****)
            hold on
            plot(****, ****)

            % Place legend under the plot, centered

            legend('****','****','****','****','Location', 'southoutside','Orientation','horizontal')
            thandle = title({'****'});
            yhandle=ylabel('****');
            saveas(gca,'C:/****.png');

What error do you get?

Are you certain that you have write permission to the top level of the C: hard drive, as would be needed to write to C:/****.png ?

Error using name (line 102) Cannot create output file 'C:\filename.png'.

Error in print (line 71) pj = name( pj );

Error in saveas (line 168) print( h, name, ['-d' dev{i}] )

Error in filename (line 222) saveas(gca,'C:\filename.png');

C:\Dropbox\ worked.

saveas(gca,'C:\filename.png');

tries to write into the top level directory of the C: drive. MS Windows does not permit users to write into that directory (not unless an administrator goes in and modifies the permissions for that directory.)

If you want to save into the "current" directory, leave out the 'C:\' , giving the file name as just 'filename.png' . If you want to save into the "current" directory of the C: drive, then leave out the \, giving the file name as just 'C:filename.png' (Note: MS Windows keeps a different "current" directory for each drive.)

Yes. How can I find where is "current directory"?

[Walter Roberson]

If you do not need to know what the current directory is for a particular drive, then just give either of the commands

cd

or

pwd

If you need to know the current directory on a particular drive then

!cd C:

or

system('cd C:')

C:\Dropbox worked.
