I have been using scilab in Japanese. I found the scilab 
"surf" plotting function cannot handle data containing 
"not a number" %nan value.
"surfl" function in plotting library 0.46 in ATOMS results 
in the same error.
Somone told me that the error neither with Scilab 5.5.2 nor with 
Scilab 6.0 was occurred without loading plotlib, with the code i 
have posted. Plotlib is known to alterate Scilab functions and make 
some of them unstable.
This error comes from the Plotlib side. 
Could you fix it?
