shiftOut is an Arduino IDE function and there is not a one-to-one match for this function included in the default MATLAB Support package for Arduino. You can try using this shiftRegister library added in the following way and see if there are equivalents to what you are trying to achieve - https://www.mathworks.com/help/supportpkg/arduinoio/ug/control-leds-with-74hc595-shift-register.html
