Please, any one tell me why my program does not work, thank you.
This is my program
a=[7 18 11 5;
2 8 10 13;
3 24 20 12;
21 1 20 17];
[m,n]= size(a);
Re=0;
i=1;
while i<=m;
j=1
while j<=n;
if ((a(i,j)<=15) & (a(i,j)>=4))
Re= Re+ a(i,j);
end
end
end
disp(Re)

In order for people to tell you why your program does not work, you have to tell them what the intended working of the program is.

Try it without loops, in a more MATLAB-ish vectorized way:
indexesToSum = a>=4 & a<=15
Re = sum(a(indexesToSum))
