No it does not work for me Error using matlab.graphics.internal.name (line 112)

Cannot create output file '.\plot.jpg'.

Error in print (line 71)

pj = matlab.graphics.internal.name( pj );

Error in saveas (line 181)

print( h, name, ['-d' dev{i}] )

Error in csvdeneme (line 10)

saveas(gcf,'plot.jpg');

I am not sure if MATLAB has any method for checking file permission.

no, the code worked I done something than It worked but I need to know how to specificy the file way. Like I would like save as in C users in dowloands section.

[Atsushi Ueno]

If you mean you want to specify current folder.

pwd

If you want to change your current folder

cd C:\Users\Dowloand\

If you want to specify absolute foler path.

cd C:\Users\Dowloand\
saveas(gcf,'plot.jpg');

Or,

saveas(gcf, 'C:\Users\Dowloand\plot.jpg');

How did you solve the error below? I don't feel good if I don't know the cause.

Cannot create output file '.\plot.jpg'.

I tried randomly thing then current folder became empty.

Invalid or missing path: C:\Kullanıcılar\yeni\plot.jpg

Error in csvdeneme (line 10)

saveas(gcf, 'C:\Kullanıcılar\yeni\plot.jpg');

than I got this error.

saveas(gcf,'plot.jpg'); this code solved my problem

As per my understanding you wanted to save a plot as a jpg file into a folder. I tried to reproduce the error you are facing but the error was not reproducible at my end.

data = csvread('test.csv');
wavelength = data(:,1);
intensity = data(:,2);
plot(wavelength, intensity);
ylabel('wavelength');
xlabel('intensity');
title('wavelength-intensity');
saveas(gcf,'C:\test.jpg','jpg')

You can go through the following documentation for more information on saveas function.
