how to delete value?

I have two arrays which are:

A=[1	1	4	2	1	3	1	3	2	2];
a=[1    3       1       2];

The outcome will be:

A=[4	1	1	3	2	2];

The very beginning elements in A turn empty based on the elements in a. It is possible by using loop and function find. Is there any other way? TIA

How you the answer using A and a?

[Walter Roberson]

Is the rule sort of like:

Look at the next element of a . Take the value there, and locate the first occurance of it in A, and change that to 0 in A. Then move on to the next element of a

Another way of saying that is that there are two 1's in a and the first two 1's in A are to be set to 0; there is one 2 in A and the first 2 in A is to be set to 0; there is one 3 in a and the first 3 in A is to be set to 0

I assume (1) your vector a indicates the numbers you want to delete in A and (2) you only delete the first number in A if any for each element in vector a.

You can use the following way to do so (delete the first element == i in A)

% A and a are given
for i = a
    A(find(A==i,1))=[]; 
end

after run the code, you will have A as expected
