operation with logical array

c=[0 0 0 0]

c = 1×4

0 0 0 0

a=[1 0 1 0]

a = 1×4

1 0 1 0

b=[0 1 1 0]

b = 1×4

0 1 1 0

b-a

ans = 1×4

-1 1 0 0

c(find((b-a)>0))=1

c = 1×4

0 1 0 0

if element a==0 and element b==1 i want to change element c in =1
Anyone can me suggest a best method to do this

[Dyuman Joshi]

c=[0 0 0 0];
a=[1 0 1 0];
b=[0 1 1 0];

c = (a==0)&(b==1)

c = 1×4 logical array
   0   1   0   0

%simplified
c = (~a)&b

c = 1×4 logical array
   0   1   0   0
