Can anyone tell me how to call a Java class main method, that takes in a command line input string, from Matlab. My simple class looks something like this:

public class Calculate_square
public static void main (String[] args){
int input, output;
input=args[0];
output=input*input;
System.out.println(output);
}
}

I call this class from the terminal like this:

$java Calculate_square 4

Thank you

did you try to simply call Calculate_square.main(...) from the Matlab command prompt?

Note that your class, as-is, will not work - you need to convert from String to int before you can multiply...
