Error message in matlab code???

??? Error using ==> iptcheckmap at 40 Function IMRESIZE expected its second input argument, MAP, to be a valid colormap. Valid colormaps cannot have values outside the range [0,1].

Error in ==> imresize>parsePreMethodArgs at 368 iptcheckmap(map, mfilename, 'MAP', 2);

Error in ==> imresize>parseInputs at 263 [params.A, params.map, params.scale, params.output_size] = ...

Error in ==> imresize at 140 params = parseInputs(varargin{:});

Error in ==> pupil_sclera at 6 x1=imresize(x,round(size(x)/2),'bicubic');

Error in ==> batch_EI_processing at 26 [a1,a2]=pupil_sclera(x);

how to fix the code????

Cheng line 6 in pupil_sclera from:

 x1=imresize(x,round(size(x)/2),'bicubic');

to:

 x1 = imresize(x, round([size(x, 1), size(x, 2)] / 2), 'bicubic');

Otherwise size(x) replies a 3D vector for RGB images and imresize expects it to be a color map. See doc imresize.
