Saving data in an array in .mat file

hi I'm working on image classification project using hue, saturation and value histograms. i get the histograms and i can save it into .mat file but i want to retrieve data to send it to nearest neighbor classifier. i can save the hue, saturation and value histograms of six bins as six values for each histogram (for each image). How can i save the 18 values(6 for hue, 6 for saturation , 6 for value) in one raw for each image (i.e for 15 images i want to have (15 * 19) denominational array in a file, the 19th column is for label). but i have no idea how to do that and if is that doable ?..... this is the code i used

%constants
savefile='hists.mat';
numberofbins=6; 
status=1; %means plant leave is not infected

rgbImage = imread('c:/seg.jpg');
% Display the original image.

% Convert to HSV color space

hsv = rgb2hsv(rgbImage); 
hsv=im2double(hsv);

% Extract out the individual channels.
h = hsv(:,:,1); 
s = hsv(:,:,2); 
v = hsv(:,:,3); 

% Take histograms
hhist=hist(h(:), numberofbins);
shist=hist(s(:), numberofbins);
vhist=hist(v(:), numberofbins);

save(savefile, 'hhist','shist','vhist','status');

% the result of the previous code as following
b=open('hists.mat')

b = 

    status: 1
     hhist: [264762 146522 3420 483 5137 292]
     shist: [233127 3829 47680 120489 4495 10996]
     vhist: [102904 4912 85358 84347 2252 140843]

what i wish to have is: 264762 146522 3420 483 5137 292 233127 3829 47680 120489 4495 10996 102904 4912 85358 84347 2252 140843 1 in one raw

thanks a lot... waiting for help :)

If I understand your question correctly, all you need to do is concatenate each of your values into one vector:

oneVectorToRuleThemAll = [hhist, shist, vhist, status];

and then save that vector like you did other ones.

You could also concatenate multiple vectors like that, vertically, into an array:

oneArray = [v1; v2; v3];

to get your 15x19 array.
