In the ADSBSimulinkExample when I connected it to RTL-SDR Receiver I got the following error: dimension mismatch

Subscripted assignment dimension mismatch: [1] ~= [0].

Error in helperAdsbNL.m (line 28)

NL(1) = find(latTable<lat,1,'first');

Error in helperAdsbRxMsgParserFun.m (line 215)

Component:Stateflow | Category:Runtime error

An error occurred while running the simulation and the simulation was terminated

Caused by:

Simulation stopped because of a runtime error.

There are no entries in which the lattable < lat.

I get the feeling it is due to being in the southern hemisphere. All the lats in the table are +ve. I have the same error.

[Walter Roberson]

The error would occur if you have any input lat which is greater than or equal to max(lattable) . In such a situation, lattable<lat is false for all entries, and find() will return empty, but emptiness cannot be stored into a scalar location NL(1)

Hi, 

I guess, there is an error in helperAdsbNL.m file. You can dive into the cause of this error by debugging through the code using breakpoints at the suggested lines in the error message. As per my understanding it’s because there are no entries of latTable which are less than lat. Hope this helps!

I get the feeling it is due to being in the southern hemisphere. All the lats in the table are +ve. I have the same error. Or am I completely on the wrong path?
