Hello there, I was given psuedocode to implement into MATLAB, but i'm having a bit of trouble with this portion. Here is what it looks like, but I cannot tell how to implement what it's asking for in MATLAB. Can someone tell me what it means in code?

G = round(rand(10)) ;
% sum of columns
sumG = sum(G,1) ;
% select s
s = sumG(randsample(10,1)) ;
% get c (column whose sum of columns is equal to c)
c = find(sumG==s) ;
% get r (zero's in the c column)
r = find(G(:,c)==0)

Notes:
  • rather than round(rand(10)), simply use randi.
  • find is not required, linear indexing is more efficient.
