My current code takes 101 images from a camera and calculates data for each image, it saves the m-file each time leaving me with 101 m-files named SigLevel0 to SigLevel101. I would like to draw a graph using only the data named "SigLevel" saved within each of these m-files that I have awkwardly also named "SigLevel".

When I open one of the generated files... ie SigLevel 13 this is what I see:

[ BrightLevel, DarkLevel, SigLevel, RMS_Noise, Noise ] = CalcImageData( 0, 1, 1392, 1040, 174, expovalue )
Signallevel = [ 'SigLevel' num2str(noofscans) '.mat' ];
         save(Signallevel);
           pause(0.01)
  end
 this is the code that runs the test, then saves the result.  How can I then read the siglevel from siglevel0 to siglevel100 and  plot it?

thanks

I think I have found out how to do this from a guide I came across that Doug put up...

http://uk.mathworks.com/matlabcentral/answers/143-how-do-i-make-a-series-of-variables-a1-a2-a3-a10

   For example, if A1 through A10 contain scalars, use:
  A = zeros(1,10);        % Not necessary, just much faster
  for i=1:10
    A(i) = % some equation
  end
