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 =
s =
s =
s =
s =
s =
s =
s =
What I need to have is simply an answer with this form : s =
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
