Compare two vector arrays and if they match set vector array 2 = nan?

time =  [0,0,0,0,2,3,4,5,5,6,7,8]
time = 1×12
     0     0     0     0     2     3     4     5     5     6     7     8
solution = [1,2,0,0,1,1,2,2,2,0,0,0]
solution = 1×12
     1     2     0     0     1     1     2     2     2     0     0     0
outcome = solution;
outcome(solution == 0 & time == 0) = nan
outcome = 1×12
     1     2   NaN   NaN     1     1     2     2     2     0     0     0

It is not clear what you want to have happen in positions where the values are equal, but the values are not 0.

if any(time==0 & solution == 0)

solution(time ==0 & solution==0)=nan;

else

return

end

Used this solution in the end, so the solution is - update where time and solution 0s are equal and if not return to script

solution(time ==0 & solution==0) = nan;
if ~any(isnan(solution)); return; end

Try this...

time =  [0,0,0,0,2,3,4,5,5,6,7,8];
solution = [1,2,0,0,1,1,2,2,2,0,0,0];
[idx]=find(time==solution);
solution(idx)=[NaN NaN]
solution = 1×12
     1     2   NaN   NaN     1     1     2     2     2     0     0     0
