sorry i can not paste the whole code this is a segment of code _______________________________________________________________
u(hour)=hour;
Clothesdryer(hour)=power_pattern(hour,1);
a1=find(Clothesdryer);

b1=find(Dish_washer);
Washing_Machine(hour)=power_pattern(hour,3);
c1=find(Washing_Machine);
oven(hour)=power_pattern(hour,4);
d1=find(oven);
iron(hour)=power_pattern(hour,5);
e1=find(iron);
Refrigerator(hour)=power_pattern(hour,6);
f1=find(Refrigerator);
Lightening(hour)=power_pattern(hour,7);
g1=find(Lightening);
Vaccume_cleaner(hour)=power_pattern(hour,8);
h1=find(Vaccume_cleaner);

>> size(a1)
ans =
1 3
>> size(a2) Undefined function or variable 'a2'. thanks torsten,i do this can u help me more as 1 9-1 3 should be ok

Check the sizes by adding
whos aa
whos a1
before the a2=aa-a1; line.
aa and a1 must have the same size, otherwise you get the error.

Zafar, you want to subtract 3 values from 9 values. That's not defined. One way to handle this would be
len = min([numel(aa) numel(a1]);
a2 = aa(1:len) - a1(1:len);
But I have no idea whether this makes sense in your code.
Maybe something needs to be fixed in the computation of aa and a1 such that they cannot have different sizes.
