I am trying to create this function in MATLAB. From a previous question, I have solved for a as "agrid2" and f(a) as "fx", whose dimensions are 600 by 1 and 600 by 2– these two vectors are absolutely correct:

`%calculating gini coefficent `

m=600; for i=1:m %expanded length of kgrid of ai previously calculated in invarden.m

mu= sum(agrid2.*fx(m,:)); gini= sum(fx(m,1)*(fx(m,2))*abs(fx(m,1)-fx(m,2)))./(2*mu); end

However, my code is returning all blank answers- what did I do wrong? Any advice is greatly appreciated!
