MATLAB: Variable “ON”

onvariable

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

Best Answer

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);
