Vector range error in matlab

I have this problem when I write range of vector, maybe someone can help me! Incorrect number or types of inputs or outputs for function 'range'.

Error in Matlabdarbs2 (line 67)

range(o);

There is my code - o=[2, 4, -3, 0, 1, 5, 7];

range(o);

mean(o);

median (o);

Works just fine for me:

o = [2, 4, -3, 0, 1, 5, 7];
range(o)

ans = 10

mean(o)

ans = 2.2857

median(o)

ans = 2

You can do

which -all range

/MATLAB/toolbox/stats/stats/range.m
/MATLAB/toolbox/shared/channel/rfprop/@txsite/range.m   % txsite method
/MATLAB/toolbox/stats/distributed/@distributed/range.m  % distributed method

to see which range function is being called. The one that I get is the one from the Statistics Toolbox.

@Bora Eryilmaz maybe I have a this error, because I have not toolbox for this working

[Steven Lord]

Yes, the range function for numeric arrays is part of Statistics and Machine Learning Toolbox.

An alternative if you don't have this toolbox available is to call bounds (which is part of MATLAB) and calculate the range from its two outputs.

[Bora Eryilmaz]

For vectors, computing the range is pretty simple. You can do it yourself without needing a command.

o = [2, 4, -3, 0, 1, 5, 7];
range = max(o) - min(o)

range = 10
