What are the best force data acquisition sensors or force plates for MATLAB?

I can point you the documentation telling you which data acquisition cards are supported in MATLAB:

MATLAB: Is it possible to add support for DAQ devices (using an SDK / Custom Adaptor) in Data Acquisition Toolbox Session Interface

There are several adaptors for popular vendors available in the toolbox and hardware support package add-ons such as National Instruments, Measurement Computing, Digilent Analog Discovery, which are listed on the hardware support page:

It is a good idea to directly contact the unsupported device manufacturer to request a custom adaptor for Data Acquisition Toolbox.

As of MATLAB R2018a it is possible to extend the hardware support to DAQ devices from other vendors, by creating a custom adaptor using the DAQ SDK.

The error is probably due to the fact that you have set TriggerConditions

set(AI,'TriggerChannel',chan(3));
set(AI,'TriggerType','software');
set(AI,'TriggerCondition','entering');
set(AI,'TriggerConditionValue',[10 10]);

I am not sure what the TriggerCondition entering stands for and what the Trigger Condition Value of [10 10] means. Could you further explain that? Should'nt TriggerConditionValue be a single number or a range?

So it is possible that your acquisition has not been triggered in the 15 seconds that you wait for it. A better check would be:

while(~AI.Logging)
 disp('Waiting for trigger');
 pause(1);
end
disp('Triggered');
wait(AI,duration*1.1);
...

But first ensure with your conditions, whether the acquisition is even getting triggered.
