Wasn't the original image the matrix you're looking for? What is an image if not a matrix of intensity values?

Accepted answer

Explain further. Do you want to crop? Are your extracted values from a rectangular or irregularly shaped region? How did you extract them? What are you going to do with this new matrix? Do you have the Image Processing Toolbox?

Where did you upload your image? http://www.mathworks.com/matlabcentral/answers/7924-where-can-i-upload-images-and-files-for-use-on-matlab-answers
