I have tried one example on integar and it worked. Now, i want to send string data to Arduino but can't do it. Can anyone help?

my trial program:

clear all;
clc;
arduino= serial('COM7','BaudRate',9600);  
 sendData =input('Enter the data ether A or B:');
 fopen(arduino);
 fprintf(arduino,'%s',sendData); 
 fscanf(arduino)    
   fclose(arduino)

Hi try this

Arduino code:

   #include <String.h>
   String str;
      void setup() {
        Serial.begin(9600);
      }
      void loop() {
        if(Serial.available() >0){
          str=Serial.readString();
          Serial.print("Received: ");
          Serial.println(str);
        }
      }

Matlab code (change to your COM port; Also the pause may need to be increased if a timeout occurs):

arduino = serial('COM3', 'Baudrate', 9600);
fopen(arduino);
pause(2)
str=('hello world');
fprintf(arduino,'%s\n',str);
recv = fscanf(arduino)
fclose(arduino);
