The interpolation interp1 command is taking wrong values.

The command line is

 Te_loop_max(i)=interp1(Ne,Temax,pbatt_const_Ne(i),'cubic')

inside a loop; The Temax,Pbatt are taking wrong values, . So the interpolation is coming 0 always. I am working on embedded function, simulink. Display and print command showing different values of Temax

   disp(fprintf('Temax=%10.3f',Temax));
   Te_loop_max(i)=interp1(Ne,Temax,pbatt_const_Ne(i),'cubic');
   disp(fprintf('Ne=%10.1f, Temax=%10.3f, pbatt=%10.3f',Ne,Temax,pbatt_const_Ne(i)));

output: Temax=    12.515Temax=    12.628Temax=    13.337Temax=    13.449Temax=    13.188Temax=    13.188Temax=    12.814Temax=    12.142Temax=    10.759Temax=     9.564   

Ne=    2000.0, Temax=  2500.000, pbatt=  3000.000Ne=    3250.0, Temax=  3500.000, pbatt=  4000.000Ne=    4500.0, Temax=  5000.000, pbatt=  5500.000Ne=    6000.0, Temax=    12.515, pbatt=    12.628Ne=      13.3, Temax=    13.449, pbatt=    13.188Ne=      13.2, Temax=    12.814, pbatt=    12.142Ne=      10.8, Temax=     9.564, pbatt=  2000.000   343

Please suggest

Generally, Ne and Temax are expected to be vectors. It is not clear why the statement is inside a loop. If you want to find interpolated values at various values of pbatt_const_Ne make it a vector too.
