I can display strings on my LCD using the matlab function printLCD(lcd,'Hello World') but I cannot define x = 123 and printLCD(lcd,x)

From my understanding you are not able to run printLCD(lcd,123). This might be because second argument of the printLCD must be a string. you can refer create LCD add-on for more information.

At least in the current version at https://www.mathworks.com/help/supportpkg/arduinoio/ug/add-lcd-library.html the code is
function printLCD(obj,message)
cmdID = obj.LCD_PRINT;
if numel(message) > 16
error('Cannot print more than 16 characters')
end
With the error talking about characters it follows that message is expected to be a character vector, not a string() scalar.

t = 0; speed = 0;
msg = sprintf('t=%.1f, speed=%.1f', t, speed);
printLCD(lcd, msg);
Watch out for the 16 character limit.
