h=double(imread('evening.jpg'));
[x,y]=meshgrid(1:size(h,1), 1:size(h,2));
result=[x(:),y(:),h(:)];

The number of rows in x,y,h are not same, so they cannot be concatenated. check your matrix dimensions.

Why? You don't need to do that (call meshgrid). You don't need to get the row, column coordinate of every single pixel in your image. Why not just call imtransform() to do skewing? By the way, you didn't even call it correctly. You mixed up x and y with rows and columns. x is columns, not rows and not gotten from size(h, 1).

Did you look at it yet? Don't you want what they call shear in their first example in the help?
I = imread('cameraman.tif');
tform = maketform('affine',[1 0 0; .5 1 0; 0 0 1]);
J = imtransform(I,tform);
imshow(I), figure, imshow(J)
