Surface chart using surf

I can make a surface chart using the surf with the following information:

I was trying to do:

surf(Ef_teta_T2(:,1),f_vector,teta_i);
...
surf(Ef_teta_T2(:,36),f_vector,teta_i);

But the message appeared:

Error using surf

Z must be a matrix, not a scalar or vector.

The graph I intend to make is the same as this:

I thank you for your help

Answer 1

Try

surf(teta_i,f_vector,Ef_teta_T2);

Can I join the curves and make one (overlap)?

[KSSV]

Yes you can.....but it depends on how your data is.

[Jacqueline Rigatto]

I will ask another question about this. Thank you KSSV

Can't you just do

surf(Ef_teta_T2);

[Jacqueline Rigatto]

This doesn't work, because I need to include the direction. Thanks Image Analyst

If you're going to use the surf(x,y,z) version with all of them being vectors, then they all need to have the same length. Yours don't.
