New to matlab. I have a program that opens many images and spits back values for each variable; each line represents a new image and has 9 variables seperated by a space. I can't find a way to get it to tell me which file it has open to give me those values. Can anyone help?

Use a cell array if you need it as a variable. For example,
for K = 1 : 10
filename = sprintf('ghoatkidney_%02d.bmp', K);
thisimage = imread(filename);
nine_stats = calculate_some_statistics(thisimage);
nine_stats_cell = num2cell(nine_stats);
outputs{K,1} = filename;
outputs{K,2:10} = nine_stats_cell{:};
end

Really new to matlab, sorry. so here are the 9 variables:
topoutward = [topleftoutward toprightoutward];
bottominward = [bottomleftinward bottomrightinward];
topinward = [topleftinward toprightinward];
bottomoutward = [bottomleftoutward bottomrightoutward];
inwardmean = mean(mean(imageedit_inward));
outwardmean = mean(mean(imageedit_outward));
topinwardmean = mean(mean(topinward));
bottominwardmean = mean(mean(bottominward));
topoutwardmean = mean(mean(topoutward));
bottomoutwardmean = mean(mean(bottomoutward));
fullratio = inwardmean/outwardmean;
topratio = topinwardmean/topoutwardmean;
bottomratio = bottominwardmean/bottomoutwardmean;
Are you suggesting I need to add this in to the "nine_stats" variable? Would the top line read filename = sprintf('*.bmp', K)?

nine_stats = [inwardmean, outwardmean, topinwardmean, bottominwardmean, topoutwardmean, bottomoutwardmean, fullratio, topratio, bottomratio];
and
filename = sprintf('%d.bmp', K);
if the file names are to be 1.bmp 2.bmp 3.bmp ... 10.bmp 11.bmp and so on.
If the file names are to be extracted from a directory then see
