export_fig: Error when setting relative path

Hi everyone!

When setting the relative path - in the export_fig function - an error occurs. Does anyone know what the problem might be? The folder 'Plots_Fig' already exists.

    % export_fig /Plots_Fig/test.png -opengl -m8;

This version of the code just works fine:

    % export_fig test.png -opengl -m8;

And this is the error message:

Error using imwrite (line 467)
Unable to open file "/Plots_Fig/test.png" for writing.  You might not have write permission.

Error in export_fig (line 552)
                imwrite(A, [options.name '.png'], 'ResolutionUnit', 'meter', 'XResolution', res,
                'YResolution', res);

Error in DataPlotter (line 129)
export_fig /Plots_Fig/test.png -opengl -m8;

export_fig /Plots_Fig/test.png -opengl -m8

does not use any relative paths. In Unix systems, a single leading / on a path name always refers to the root of the file system. If you want a relative path, either use ./ or leave off the leading / . So either

export_fig ./Plots_Fig/test.png -opengl -m8

or

    export_fig Plots_Fig/test.png -opengl -m8
