How to read a variable from Arduino or a PWM value from Arduino in Matlab

Hi Mathworkes
I made an RC using nrf24l01 and Arduino and now I need to see what the transmitting Arduino send as a information to my receiver. In Arduino IDE I use:
radio.read(&data, sizeof(MyData));
my data are:
struct MyData {
byte latitude;
byte longitude;}
I use this to acquire the information that I receive and, in the same code, I transform that in PWM values to control motors.
Is it any method to read this values em Matlab? I need it to create a control system.
I'm really grateful for you help.

Establish the serial communication between Arduino and MatLab. So that you can read and use the values for creating your control system. For example:
//From your Arduino end, send the data
serial.begin('Baud rate')
if (serial.available())
serial.print('Mydata');
end
%% MatLab end, receive the data
ser=serial('Com port ', 'Baud rate')
fopen(ser);
output = fscanf(ser);
fclose(ser);
delete(ser);

Something you could do like this to read all the data until you close the serial connection
result=[];
if ~isempty(output)
result=[result;output];
end
