Why does my code only come out with one result?

function [siftedData, siftedMean, siftedStd, siftedNorm] = project2(rawData, categories, selectedCategory)
    
    rawData(categories == selectedCategory) = [];
    
    siftedData = rawData;
    
    siftedMean = mean(rawData);
    
    siftedStd = std(rawData)
    
    siftedNorm = (rawData - siftedMean) ./ siftedStd;
    
    
   %call with project2([1.2, 3.4, 7.6, 8.4], [1, 0, 0, 1], 1) 
end

I'm supposed to have 4 outputs but when I call the function I only get the result of siftedData. Even if I use siftedData or rawData in the equations I still only get one answer.

Call it as:

[siftedData, siftedMean, siftedStd, siftedNorm] = project2(rawData, categories, selectedCategory)

and all the outputs will appear in your workspace. The default behaviour for functions with several outputs is to only return the first output if there is only one assignment. If you want all of them, you need to ask for all of them.
