Save your plots or figures to JPEG

Having issues viewing MATLAB figures or saving them? Then use this JPEG generating function.

This function takes in a figure and saves it to a JPEG file. You can specify up to 3 parameters: the filename, quality level and a file handle to your figure. The function returns the current filename.

If no parameters are specified then the function creates a dummy JPEG file using default settings. This is a FFT plot of a sine wave. Hence the function name.

You can also just give fftFig one parameter (i.e. handle) or two parameters (i.e. handle + filename).
%
% EX:
% >> handle = figure;
% >> plot([1:5]);
% >> fftFig(handle,'afile1',100)
% ans =
% afile1
%

I have zipped the dummy JPEG figure in with the MATLAB-file for your convenience.
