hi I have 2 matrices A and B.
A=[0 0.375 0.405 0.452 0.500 0.530 0.577 0.623 0.639 0.670 0.701 0.717 0.748 0.779]
B=0:01:end
I want to find nearest number of A to 0.1 and then to 0.2 and then to 0.3 and ...
in this case the nearest numbers to 0.1 and 0.2 is 0.but I want a program that find the nearest number to 0.1 and put that number away and then find the nearest number to 0.2 and so on.
can you help me?

What's the purpose of B? What is "end"?
Anyway, using A, try this:
clc;
A=[0 0.375 0.405 0.452 0.500 0.530 0.577 0.623 0.639 0.670 0.701 0.717 0.748 0.779]
for k = 1 : length(A)
[~, nearestIndex(k)] = min(abs(A - k/10));
end
% Display in command window:
nearestIndex

k is an index. Indexes can't start from 0 since they have to be integers starting at 1. However you can make another variable that is just k-1 if you want.
But anyway, that code doesn't use B like my latest code, so it's not right anyway.
