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...

The linked page already tells you the complete content of the SCALE function and exactly where to write it.
