I am trying to pass the value of the matrix one by one for run my function but it shows error!

I_mot=0.81772*ones(20,1);

alpha0=60 + 60*rand(20,1); %Stores random value in 20 by 1 matrix

alpha1=alpha0;

for i=1:20

tbeg=0;

tsim=3;

alpha(i)=alpha1(i,1);

[I_steadystate,Ir_rms]=motor_model(alpha(i),tbeg,tsim);

I_actual(i,1)=I_steadystate(i);

end

I_actual

The error is:

?? Undefined function or method 'motor_model' for input arguments of type 'double'.

Error in ==> test at 9
    [I_steadystate,Ir_rms]=motor_model(alpha(i),tbeg,tsim);

Is motor_model.m on your path? What does this command give you:

which motor_model

?
