I#m trying to figure out how to work with tif files in Matlab. I tried following this example:
But when I try executing this code:
[A,R,cmap] = readgeoraster('U2012_CLC2006_V2020_20u1.tif');
geoshow(A,cmap,R)
I get this Error Message
Error using repmat
Requested 46000x65000x3 (8.4GB) array exceeds maximum array size preference. Creation of arrays greater than this limit may take a long time and cause MATLAB to become unresponsive.
Error in checkImage (line 39)
A = repmat(A,[1 1 3]);
Error in validateTextureComponent (line 70)
dataArgs{imageIndex} = checkImage( ...
Error in validateGeoRasterData (line 23)
[dataArgs, R, imageIndex, rules] = validateTextureComponent( ...
Error in georastershow (line 144)
validateGeoRasterData('geoshow', dataArgs, displayType);
Error in geoshow (line 242)
h = showFcn(varargin{:});
Error in tif (line 6)
geoshow(A,cmap,R)
What should I do to fix this error? Is the file simply too big?

Hey Michael,
You can specify the size of maximum array under 'Preferences'.
