Hello,
I would like to generate a contour or 3-D plot for a large data set.
I have a matrix B, where size(B)= 483060 4
The parameters contained in B are as follows:
if true
time=B(:,1); %first column is temperature
sy=B(:,2); %second column is distnce in y
tl=B(:,3); %third column is temperature l
te=B(:,4); %fourth column is temperature e
end
I would like to 3-D plot of both tl and te in time and space (sy).
I have tried contour3(time,sy,tl) but recieve the error
"Z must be at least a 2x2 matrix."
Best,
A

Try plot3 or scatter3
For a contour plot you need a nxn matrix

scatter or scatter3 can do that.
