Matlab just says there is an error, but I don't see one. How do I know more about the error.

Error in GetSteamZoneParameters (line 7) [ tcD ] = FindtcD( fhv );

I do not get any more description.

The GetSteamZoneParameters function works fine when I call it through the command window. But when I call this function through SAGD.m I get the error.

This code is a part of a simulator for steam injection in oil fields.

Try calling, on the command line

 dbstop if error

The program will stop and let you see what's going on at the point it throws an error.

This did not help. The debugger just pointed to the line where the error occurred.

Error in GetSteamZoneParameters (line 7) [ tcD ] = FindtcD( fhv );

Output argument "angleOfInclination" (and maybe others) not assigned during call to "H:\MATLAB\CSI-mine\GetSteamZoneParameters.m>GetSteamZoneParameters".

Error in SAGD (line 29) [Qi, angleOfInclination, steamZoneRadius, steamZoneVolume ] = GetSteamZoneParameters( Qi,fhv, tD, cycle, rinj, Xinj, time, injTime, Tavg, Ti, Mr, Ts, reservoirThickness, length1);

Error in final (line 81) [ Cw, fhv, Mw, Mo, Mr, s,tD , tcD, WOR, OSR ] = SAGD( fPD,qo,length1, cumTime, cum_oil_tot,cum_wat_tot, cum_steam_tot, cycle, Ts,Ti, Xinj, API, Swi, phi, alpha,...
