MATLAB: Check if two variables are not equal to zero.

checking vector elementsMATLABvector

I have the vector e.g

A=10
B=4
C=0
D=4
V = [A,B,C,D]

How would I check if more than two values equal zero.

Best Answer

 ind=find(V==0)
 size(ind)

 sum(V(:)==0) %this will give the number of zeros

MATLAB: Set an empty cell array equal to zero.

Actually, the cell array itself is not empty, it holds an empty array. And, empty isn't a string value anyway so that comparison wouldn't work even if there were an equality test for empty (which there isn't). All in all, that's barking up the wrong tree entirely... :)

if isempty(stopcodon1{:})
  ...

should lead to nirvana. Or, of course, modify program logic to not create the cell variable if the array itself is empty (altho that may break some other symmetry in algorithms, granted).
