Display error

[Arun Mallya]

I computed the FFT of an image and wanted to display it. I however obtained the following error message:

"

>> figure(1), imagesc(log(abs(fftshift(im1_fft)))), axis image, colormap jet

Error using image

Error using image

TrueColor CData contains element out of range 0.0 <= value <=1.0

Error in imagesc (line 19)

    hh = image(varargin{1},'CDataMapping','scaled');

"

How can I fix this? 

Thanks!

image is black&white or color? if the later one, it may cause that error I think.

Yeah it's color.

Right, you can display only scaled images that have one channel (NxMx1, not NxMx3)
