Error using -
Matrix dimensions must agree.
Error in mmmmmmmtest1m1m (line 326)
a2=aa-a1;
i am surprised why my a2 not calculating my aa value is ok and a1 but the aa and a1 matrices are not equal when i minus them it gave above error ,i spend 10 days on it but this issue is not solving
---------------------------------
Code Hints:-
u(hour)=hour;
Clothesdrye(hour)=power_pattern(hour,1);
a1=find(Clothesdrye);
------------------------------------------------
stereo=[1 0 0 0 0 0 0 1 1 1 1 1 1 1 1 1 1 0 0 0 0 1 1 1];
Fan=[0 0 0 0 0 0 0 0 1 1 1 1 1 1 1 1 1 0 1 0 0 0 1 1];
aa=find(stereo);
bb=find(Fan);
-------------------------------------------
Index
a2=aa-a1;
b2=bb-b1;
% len = min([numel(aa) numel(a1)]);-----1
% a1 = aa(1:len) - a1(1:len);-----2
%a1=linspace(0,14,14);%# 14 values spanning the range 0 to 14------3
%a1=[1 8 9 10 11 12 13 14 15 16 17 22 23 24];----4
i have also tried from 1 to 4 but in vain
i am pasting the bit pattern of variables may be helpful for commenters/guiders below.

Your aa has is a 14 element row vector. Your a1 is a 3 element row vector. What result are you expecting when you subtract them?
Hint: bsxfun()
