Hi everybody, I am using the following for loop code
for j = 3:1:6
A(j)=1*10.^(-j);
end
This gives me A=[0 0 0.001 0.0001 1e-05 1e-06]
I need the value of A for j = 3, 4, 5, and 6. In the above result my desired values are (0.001 0.0001 1e-05 1e-06). I don’t know from where the first 2 values (0 0) come, which are not required here. Any guidance will be appreciated thanks

Reason: The first two elements are zero because you assign the values from index three so matlab assigns the first two values as zeros because matlab index starts from one.
You don't need loop at all:
A=10.^(-(3:6));
But if you insist one then:
n=3:6;
A=zeros(1,numel(n)); % preallocate
for j = 1:numel(n)
A(j)=10.^(-n(j));
end
A
Gives:
A=[ 0.001, 0.0001, 0.00001, 0.000001]
