adjust for matrix input
显示 更早的评论
How do I in a spimple way adjust this below to be able to handle a matrix as input, for example if:
p_t2=rand(2,1000)
pt2=rand(2,40)
JJ=[];
for z=1:40
for v=1:25
XX=p_t2(v)./pt2;
JJ=[JJ sum(XX)];
end
p_t2(1:25)=[];
pt2(:,1)=[];
end
I want the output JJ be a matrix with dimension (2,1000)

Use sum(XX,2) instead of sum(XX)
p_t2=rand(2,1000);
pt2=rand(2,40);
JJ=[]
for z=1:40
for v=1:25
XX=p_t2(v)./pt2;
JJ=[JJ sum(XX,2)];
end
p_t2(1:25)=[];
pt2(:,1)=[];
end

What do you mean: it's not working
What was the result?

So, Lukas, I suggest that you explain what you want to calculate. We cannot guess it.
