Of course you could always look at the variable in the variable editor and see the whole thing .

Or try this. For some upper left row and column:

croppedMatrix = matrix(row1:row1+511, column1:column1+3999);

what is the row1 and column1... it is showing like undefined variable or function 'row1'???

You said you wanted the matrix cropped to 512*4000 but you did not say where those 512 x 4000 should be positioned within the original matrix. You would define row1 as the first row you want included and column1 as the first column you want included. If you want the "top left" of the matrix that would be

croppedMatrix = matrix(1:512, 1:4000);

The limitation of 53866 is only in the variable editor. To see the whole matrix you can give its name at the MATLAB prompt.
