if true
% code
endok. Actually variable R1 is R1=[1 2]. It shows error in display. but I inspired this from matlab help page as
Example ------- % Read and display the Boston GeoTIFF image. % Includes material (c) GeoEye, all rights reserved. [boston, R] = geotiffread('boston.tif'); figure mapshow(boston, R) axis image off
But R here is R=[1 1], shows display. but in my script, if R1 size R1=[1 2], I got error.. help me to find error...

Alright, but same question just different variable name:
What does it say if you do
whos R1
whos boston
right after you read it in? Simply giving it a variable name of R1 instead of R for the return argument is not going to cause it to fail.
