good after noon everyone....
I wrote this script that must combines 3 RGB images into one image note that 1.png, 2.png and 3.png are images of same dimentions (500 x 666) I need the final image to show the three images as one image but with reasonable dimensions
Rows = 1;
Cols = 3;
Cell = cell(Rows,Cols);
for i = 1:Rows*Cols
imageName = sprintf('%i.png',i);
imgCell{i} = imread(imageName);
bigImage = mat2cell(imgCell);
However I received this error:
Error using imageDisplayValidateParams
Expected input number 1, I, to be one of these types:
double, single, uint8, uint16, uint32, uint64, int8, int16, int32, int64, logical
Instead its type was cell.
Error in imageDisplayValidateParams (line 11)

Error in imageDisplayParseInputs (line 78)
common_args = imageDisplayValidateParams(common_args);

What do you want to do? Do you want to average them together? Stitch them side-by-side? Have you seen montage(), imshowpair(), and imfuse()? Explain more what you want to do and I can give a more specific solution.

Because you're passing imshow() a cell array , and in each cell of the array is a chunk of an image - a sub image. imshow() wants the images themselves, directly, it doesn't want a cell array of a bunch of cells that each contain an image. A cell array is like a collection of buckets, and you can thrown whatever you want (images, strings, etc.) into any of the buckets. Please read the FAQ to get a good intuitive feel for what cell arrays are:

You can display a cell array of images using imdisp.

I think you may have not visited the link he gave to his File Exchange and downloaded the file.
Or if you did, you put it somewhere not on the search path.
