Hi all,
I tried to find 'range' of a matrix but always return error. For example;
Data=rand(10,10)
range(Data,'all') always return the follwing error;
''Error using max
Invalid option. Option must be 'omitnan' or 'includenan'.
Error in range (line 20)
y = max(x,[],dim) - min(x,[],dim);''
Does anyone knows whats the problem please?
thanks

Hi,
the option
'all'
was introduced in R2018b - in earlier releases you can not use this feature. Make sure to look in the documentaion that corresponds to the release you use to avoid this issues.

Best regards

% 2D Array
ROI=rand(10,10)
Range1 = range(ROI(:))
% 3D Array
ROI=rand(10,10,3)
Range2 = range(ROI(:))
