When I write command:
configurePin(mypi, 13, 'PWM');
I receive error:
">> configurePin(mypi, 13, 'PWM');
Error using raspi/recvResponse (line 697)
Unable to configure pin for PWM output.
Error in raspi.internal.PWMBase/initPWM (line 24)
recvResponse(obj);
Error in raspi/configurePinPWM (line 830)
initPWM(obj,pinNumber,frequency,0);
Error in raspi/configurePin (line 489)
configurePinPWM(obj,pinNumber,frequency);

Notice that 13 is not on the list of Available Digital Pins in the example https://www.mathworks.com/help/supportpkg/raspberrypiio/ref/configurepin.html#bvdit9u.bt548he-20 .
The list of GPIO pins is different for different boards and different ways of talking about the pins. In at least one of the pin numbering schemes, pin 13 is MISO, which is for SPI interfaces.

I was trying "Wiring Pi pin 23" - nothing
I also was trying use any number from this list:
"
>> mypi.AvailableDigitalPins
ans =
2 3 4 5 6 7 8 9 10 11 12 13 14
15 16 17 18 19 20 21 22 23 24 25 26 27
"
but answer was old
