NaN means in image resize in matlab? -

-

what code mean?? code written in matlab.

 citra=imresize(citra,[400 nan]);

i know image (citra) resize 400. but, nan? that's mean?

read docs: http://www.mathworks.com/help/images/ref/imresize.html

either numrows or numcols may nan, in case imresize computes number of rows or columns automatically preserve image aspect ratio.
