This code is giving me error message (FUNCTION keyword use is invalid here, this might cause later message about END).
df=findobj('tag', 'edit3 ');
sdf=get( df,'string');
fg=['c:/users/gabs/documents/matlab/Segmented' sdf];
vv =imread(fg);
if ndims(vv)==3
I=rgb2gray(vv);
else
I=vv;
end
vv=I;
N = normalise(vv,O,l); % normalise to have zero mean, unit std dev
yu=['Originallmage:', sdf];
po=['c:/users/Deji/documents/matlab/Normalized ',sdf];
imwrite(N,po );
%subplot(1 ,2,1), imshow(I,'initialmagnification' ,215), title(yu);
imshow(N),title(strcat(po ));
% This function normalizes the image to desired mean of 0 and variance of 1
function gb = normalise(image,desiremean,desirevar)
if ~(margin == 1 || margin == 3)
error('No of arguments must be 1 or 3');
end
if margin == 1 % Normalisc 0 - 1
ifndims(image) ~= 3; % Assume colour i.mage
else % Normalise to desired mean and variance
if ndims(image) == 3 % colour image?
error('cannot normalise colour image to desired mean and variance');
end
if ~isa(dsafimage,'double')
image = double(image);
end
image = image - mean(image(:));
image = image/std(image(:)); % Zero mean, unit std dev
gb = desiremean + image*sqrt(desirevar);
end

Where is this code located? If you have it in a script or at the command line, that would explain why you get that error.

save this function
function gb = normalise(image,desiremean,desirevar)
if ~(margin == 1 || margin == 3)
error('No of arguments must be 1 or 3');
end
if margin == 1 % Normalisc 0 - 1
ifndims(image) ~= 3; % Assume colour i.mage
else % Normalise to desired mean and variance
if ndims(image) == 3 % colour image?
error('cannot normalise colour image to desired mean and variance');
end
if ~isa(dsafimage,'double')
image = double(image);
end
image = image - mean(image(:));
image = image/std(image(:)); % Zero mean, unit std dev
gb = desiremean + image*sqrt(desirevar);
end
then run this part of your code
df=findobj('tag', 'edit3 ');
sdf=get( df,'string');
fg=['c:/users/gabs/documents/matlab/Segmented' sdf];
vv =imread(fg);
if ndims(vv)==3
I=rgb2gray(vv);
else
I=vv;
end
vv=I;
N = normalise(vv,O,l); % normalise to have zero mean, unit std dev
yu=['Originallmage:', sdf];
po=['c:/users/Deji/documents/matlab/Normalized ',sdf];
imwrite(N,po );
%subplot(1 ,2,1), imshow(I,'initialmagnification' ,215), title(yu);
imshow(N),title(strcat(po ));
