Hello– I have a question and it is very important to me. I will appreciate if anyone could help me on this issue! WE have two matrices: one is r(40*80) and the other one is s(8*1) Also we know that 8 rows of matrix r are zeros. ( for example : rows number 6,9,19,23,25,32,33,38 )
I need a code to just write the numbers of zero rows ( which are listed above ) in the s matrix in the order. I wrote this:
s=zeros(8,1);
for row_number = 1:40
A=r(row_number,:); [i,v,c]=find(A); row_number; max(v); min(v); c; if isempty(max(v)) for h=1:8 s(h,1)=row_number; hold on end s end
and this is the answer I got!
s =
6 6 6 6 6 6 6 6
s =
9 9 9 9 9 9 9 9
s =
19 19 19 19 19 19 19 19
s =
23 23 23 23 23 23 23 23
s =
25 25 25 25 25 25 25 25
s =
32 32 32 32 32 32 32 32
s =
33 33 33 33 33 33 33 33
s =
38 38 38 38 38 38 38 38
What I need to have is simply an answer with this form : s =
6 9 19 23 25 32 33 38
the reason I use find(A) was to do some calculations with min(v) and max(v) for rows with non zero elements. I will be thankful of anyone helping me with this. Best, Homayoon
