img=imread('flair.jpg');
gaborArray = gaborFilterBank(5,6,39,39);
featureVector = gaborFeatures(img,gaborArray,1,1);
img_size=size(img(:));
fv=reshape(featureVector, size(img_size),30);
out=kmeans(fv,5); %k-means where k=5
%Apply histogram of texton map within each super pixel
res=hist(out,5);
disp(res)
Error: Error using reshape Size arguments must be integer scalars. Error in texton (line 8) fv=reshape(featureVector, size(img_size),30);

This
img_size=size(img(:));
will return a 1x2 row vector equivalent to this:
[numel(img),1]
Then you get the size of the 1x2 vector img_size using
size(img_size)
which will therefore always return the vector [1,2], which is not a scalar, and is thus an invalid input to reshape. Note that the syntax size(X) will always return an 1xN vector, where N>=2.
It is not clear what you are trying to do.

Put the new size into one vector:

[size(img_size),30]

it works for me:

fv = reshape(featureVector,[size(img),30]);

As its help shows, reshape does not support both multiple inputs and a non-scalar input at the same time: either all separate inputs need to be scalar (one may be empty), or use one non-scalar input.
