That function is in the Image Processing Toolbox, which evidently you do not have. Type

>> ver

to see what toolboxes you have installed.

Try this to verify whether or not you have the Image Processing Toolbox installed:

% Check that user has the specified Toolbox installed and licensed.
hasLicenseForToolbox = license('test', 'image_toolbox');	% Check for Image Processing Toolbox.
% hasLicenseForToolbox = license('test','Statistics_toolbox');	% Check for Statistics and Machine Learning Toolbox.
% hasLicenseForToolbox = license('test','Signal_toolbox');	% Check for Signal Processing Toolbox.
% hasLicenseForToolbox = license('test', 'video_and_image_blockset');	% Check for Computer Vision System Toolbox.
if ~hasLicenseForToolbox
	% User does not have the toolbox installed, or if it is, there is no available license for it.
	% For example, there is a pool of 10 licenses and all 10 have been checked out by other people already.
	ver % List what toolboxes the user has licenses available for.
	message = sprintf('Sorry, but you do not seem to have the Image Processing Toolbox.\nDo you want to try to continue anyway?');
	reply = questdlg(message, 'Toolbox missing', 'Yes', 'No', 'Yes');
	if strcmpi(reply, 'No')
		% User said No, so exit.
		return;
	end
end

MATLAB: I want to repeat the input command and the if-else statement. The input has to be positive and must include 0 and not include inf.

cond=1;
while cond==1
    A=input('Enter the Code: ');
    if A>=0 && A~=inf
       B=A
       cond=0; 
    else
       disp('Invalid Code');
    end 
end

A=input('Enter the Code: ');
while A<0 || A==inf
       disp('Invalid Code');
       A=input('Enter the Code: ');
end 
B=A;
