serial reception problem.

hello everyone, i am trying to transmit the analog input data to matlab. i am able to receive the data in matlab too, but even after the analog input is changed the data read in matlab doesnot change. i tried the same using serial monitor it worked perfectly. pls help me to solve this problem. here is the sketch of my project.

int analogInPin1 = A0;
int analogInPin2 = A1;
int analogInPin3 = A2;
int analogInPin4 = A3;
int analogInPin5 = A4;
int analogInPin6 = A5;

int sensorValue1 = 0;
int sensorValue2 = 0;
int sensorValue3 = 0;
int sensorValue4 = 0;
int sensorValue5 = 0;
int sensorValue6 = 0;

int outputValue1 = 0;
int outputValue2 = 0;
int outputValue3 = 0;
int outputValue4 = 0;
int outputValue5 = 0;
int outputValue6 = 0;

void setup() {
// initialize serial communications at 9600 bps:



void loop() {
// read the analog in value:
if(Serial.available() > 0)
sensorValue1 = analogRead(analogInPin1);
sensorValue2 = analogRead(analogInPin2);
sensorValue3= analogRead(analogInPin3);
sensorValue4 = analogRead(analogInPin4);
sensorValue5 = analogRead(analogInPin5);
sensorValue6 = analogRead(analogInPin6); // map it to the range of the analog out:

outputValue1 = map(sensorValue1, 0, 1023, 0, 255);
outputValue2 = map(sensorValue2, 0, 1023, 0, 255);
outputValue3 = map(sensorValue3, 0, 1023, 0, 255);
outputValue4 = map(sensorValue4, 0, 1023, 0, 255);
outputValue5 = map(sensorValue5, 0, 1023, 0, 255);
outputValue6 = map(sensorValue6, 0, 1023, 0, 255); // change the analog out value:

for(int i=0;i<30;i++)








Why are you printing the same values thirty times?
Why is your code so long?
Where are the code tags?
What character do you send to the Arduino to trigger readings, and are you actually sending it?

i need to continuously monitor the analog input device and store the resulting value in matlab object.

That doesn't answer any of my questions.

the data that i am transmitting are integer values

Again, doesn't answer my questions.
The thread title suggests a reception problem, but you are showing transmit code.

sorry for the inconvenience, i meant to say reception problem in matlab... it perfectly reads the value and prints it in serial monitor, but not in matlab

So, the problem is with the Matlab code.
Have you tried the Matlab forum?

yes, i have tried sir. i didnt get the solution to my problem.

Maybe you didn't answer any of their questions either.

may be sir, i have tried my best. thank you for you valuable time sir..
