Range of a matrix

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.

Thanks for your response. But I am using 2017b

So use:

range(Data(:))

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

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