hi, I havea series of jpeg images that I am trying to enter and view in matlab (eventually, I would love to try to tile them). I am using he imread function to load. the imshow function is not working. I am getting the following error
Error in ==> basicImageDisplay at 9 hh = image(xdata,ydata,cdata, ...
Error in ==> imshow at 246 hh = basicImageDisplay(fig_handle,ax_handle,...
I tried the following: - changing rgb to gray scale to reduce the dimesnions of the matric - renaming the m file - reducing the size of the file/image i am importing. I ended up with a 600x800 pixel image. is that still too big?
Any comment on the above would be appreciated. thanks m

You give the start of each error message, but not the most important part - what the error is. Could you please include the rest of the message?

Also, how is IMSHOW being called? Give the calling syntax, and a description of each argument...

You probably have your own routine image.m on your MATLAB path. You need to get rid of your personal image.m
Use
which -all image.m
to see which image() is being invoked.

Based upon your concerns about reducing sizes, the error message you are getting may be one about running out of memory. If that is happening for an image as small as 600x800 then you likely have your own routine named "image" on your path.
which -all image
The same kind of problem could also trigger messages about indexes out of range.

Thanks gentlemen for your replies.
the script I am writing is really simple:
img1=imread('test.jpg'); % reading the image file which is a grid % of squares
img1grey=rgb2gray(img1); % changing to gray scale
img1grey=double(img1grey);
figure(1)
imshow(img1grey;
the errors I am getting are:
??? Attempt to call constructor image with incorrect letter case.
Error in ==> basicImageDisplay at 9
hh = image(xdata,ydata,cdata, ...
Error in ==> imshow at 246
hh = basicImageDisplay(fig_handle,ax_handle,...
thanks

Thanks Walter. I have seen this as a suggested solution somewhere else as well. I tried to rename my m file and the matrices containing the image data...without luck.
