Dimensional Problem with simple coefficient equation
1 view (last 30 days)
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
for i=1:m %expanded length of kgrid of ai previously calculated in invarden.m
However, my code is returning all blank answers- what did I do wrong? Any advice is greatly appreciated!

For two summations, you will need two for loops. Also , you are not accumulating the sum. Variable gini is getting new value for every iteration. So you are losing the data from previous iterations.
For an equation like G= , the code will be like this:
for i = 1:40
for j = 50
sum = sum + (i+j);
G = sum;
Hope this helps
