Passing Inports to output with Matlab Sim command

In checking model results am getting the outport yout data, however I need interpolated inport data to show inputs vs outputs. Using sim command with C as a structure since I have a mix of dimensions and classes.

[tout,xout,yout]= sim('mymodel.mdl',tend,simset('OutputVariables', 'txy','SaveFormat','StructureWithTime'), C)

Have tried unsuccessfully to use signal logging. I could use a simout block, though this is a bit messy and the target environment is real time.

try

[tout,xout,yout]= sim('mymodel',tend,simset('OutputVariables', 'txy','SaveFormat','StructureWithTime'));

The argument C is not needed. The output structure with time is in xout, yout.

Update:

Make a simple example, one Inport, time a Gain of 2 and then Outport. Use default setting, enable signal logging, Input [t u], Time tout, Output yout.

t=(0:0.1:2*pi)';
u=sin(t);

sim('test');
figure(1);
plot(t,u,'r',tout,yout,'g');
[Stout,Sxout,Syout]= sim('test',10,simset('OutputVariables', 'txy','SaveFormat','StructureWithTime'));
figure(2);plot(t,u,'r',Syout.time,Syout.signals.values,'g');
C=Syout;
[Stout,Sxout,Syout]= sim('test',10,simset('OutputVariables', 'txy','SaveFormat','StructureWithTime'),C);
figure(3);plot(C.time,C.signals.values,'r',Syout.time,Syout.signals.values,'g');

C in this case is ut, required to define the inputs. xout only contains states as a function of time no inport data is coming across.

C is a structure with logicals, doubles and some are of multi-dimensions.

from help:

[t,x,y] = sim(model,timespan,options,ut);

Thank you for point it out. I was running the f14.mdl which doesn't have root level Inports.

It worked for me. See updates in my answer. Also, signal logging works too.
