Let's say I have an array A defined as
A = [0 2 5 7 8]
Let's say I haven array B defined as
B = linspace[0,10,100]
Now I want to perform an operation on each value in B that is greater than or equal to the previous value in A. For simplicity, let's just say subtraction.
Basically I want to perform the following operations (and store the results as an array):
(0-0)
(.1-0)
(.2-0)
...
(1.9-0)
(2-2)
(2.1-2)
...
(9.8-8)
(10-8)
Because of other code involved, I want to index over the values of A like so
n=length(A);
for j=1:n
x0 = A(j);
% Now I want to subtract each value in B minus the appropriate x0 and save all the results as an array
end
How could I accomplish the rest of the desired procedure?

How about the following?
C = B'-A;
C = C(:);

This works for subtraction, but not general operations within the scheme provided.

It's not clear for me.
Could you tell us more details on your problem and what the output should be or looks like?
