Simulink, error while parsing Matlab function

Errors occurred during parsing of MATLAB function 'Subsystem1/MATLAB Function2'(#34)

This is the code in the Matlab function:

function [Thrust1,Torque1] = fcn(PWM_M)

Thrust3 = zeros;
Torque3 = zeros;

PWM = [1000 1200 1500 1600 1650 1700 1750 1800 1850 1900 1950 2000];

Frec_M = [0 50 75 84 91 94 100 109 113 119 121 125];

RPM_M = Frec_M * 60;

Thrust_all = 8.9e-7*RPM_M.^2.3314;

Torque_all = 1.0798e-005*Thrust;

Thrust1 = interp1(PWM,Thrust_all,PWM_M,'spline');
Torque1 = interp1(PWM,Torque_all,PWM_M,'spline');

end

What are the error msgs? Where is the variable Thrust declared or assigned?
