Sorry, I did not cross-check the imresize calling sequence. Instead of
m,n it should be [m,n] or [n,m] -- rows first and then columns.

Did u mean do it like this

??? tr_space(:,i) = reshape( imresize(tmp_tr .', [m,n], [], 1);
|
Error: Unbalanced or unexpected parenthesis or bracket.

Ive tried reversed [n,m] as well but it still produce same error.

When I use the reshape statement the (i) value turn out to be only two instead of 100 since i used 100images. Any suggestion to be able to read the whole set..Please advice and thank you in advance.

tr_space(:,i) = reshape( imresize(tmp_tr .', [m, n]), [], 1);

Thank you very much for your help. I try to crop the image using the same statement but it gives me error. Can you tell me how to crop the image instead of resize it.

doc imcrop


X2 = imcrop(X, map, rect) crops the indexed image X. map specifies the
colormap used with X. rect is a four-element position vector [xmin ymin
width height] that specifies the size and position of the cropping
rectangle.


And be sure to read the Remarks section of the documentation.
