how to modify a variable data by scale function like data= scale(data); I have to modify scale function for variable data

how to modify a variable data by scale function like data= scale(data); I have to modify scale function for variable data

Actually i am writing a matlab code for training in Matlan onramp and didn't getting how to solve the above

Given only the above information:

function scaled = scale(data)
   scaled = data ./ 1000;
end

The 1000 should be adjusted to whatever is appropriate for your situation.

FYI, in a more general case (not just writing a scaling function for a MATLAB Onramp exercise) the rescale and/or normalize functions could be useful.

how to recall scale function if it is unused.

function scaled = scale(data)

scaled = data ./ 1000;

end

When i try to submit my code for onramp exercise this message appears: Has the variable data been correctly modified by the scale function?

[Walter Roberson]

Looks like the exercise wanted some different scaling. Perhaps multiplying by 173, or dividing by 32768...
