simple trapz function integration problem
显示 更早的评论
Hi all,
I have simple code to integrate the matrix using trapz. I don't want to include NaN number on the matrix in the integration, but the code just give zero value at the end.
Here is the code:
x=[1 3 4 NaN; 5 6 8 7];
for i=1:2;
for j=1:4;
if isnan(x(i,j));
y(i,j)=trapz(x(i,j));
else y(i,j)= NaN;
end;
end;
end;
Maybe anyone can help, thanks.

Try to use this code:
x=[1 3 4 NaN; 5 6 8 7];
s1= trapz(x(1,1:3))
s2= trapz(x(2,:))
