I have an array and I'm trying to make another array consisting of mean values of the first array.
I have some code i used to try and solve it myself using a for loop
A= (1:10);
b = 2;
c=1;
for i = 1:10
d(:,i) = mean(A(b:c));
b=b+1;
c=c+1;
end
Any suggestions or changes would be much appreciarted as this code currently doesn't work.

Yes, A(b:c) is A(2 : 1) which is null since your starting index, 2, is after your ending index, 1. So that's why it didn't work.
