Re: 3D plot from a matrix

[guido.bonalumi]

Ok, I am trying your solution. I have a strange problem though:
I have 3 matrices containing the values for Z, U, and V, all three created
in the same way (copying the value from excel into a .dat file). I do not
understand why Z it is read as matrix while U and V like string (I used
/textinfo/ to know the argument type). To read them I use these 3 lines:

/Z=load("data.dat");
tg=("tg.dat");
rad=("rad.dat");/

Any idea? Otherwise
