Variable "ON"

Question

Hey

I have 2 arrays, A and B matrices of equal lengths. Now, I need to generate C of same length where,

A = series of zeros with clusters of 10-15values spread out. (Sensor ON readings)

B contains all values. (Fuel amts at all conditions)

So something like,

if A is ON

   read those B values
   C % doing that calculation

end

Answer 1

First, create C:

C = zeros(size(B));

Then use this command to assign elements of B associated with nonzero A values into the corresponding locations in C:

C(A~=0) = B(A~=0);

If the values in A are not exactly zero but really tiny, then create a threshold

thresh = 1e-6; % 10^(-6) for example

And use this threshold as follows

C(abs(A)>thresh) = B(abs(A)>thresh);
