what is the function of X and Y equation?How to describe that function?

1)  Y=linspace(dy,dy*yNum*1000000,yNum);
2)  X=linspace(dx,dx*xNum*1000000,xNum);
3)  X=rot90(X,3);

linspace() create linearly spaced numeric array. In this case, the first element will start with dy and the last element is dy*yNum*1000000. And in between these two values, you will get yNum values. For example

firstElement = 0;
lastElement = 1;
num = 10;
X = linspace(firstElement, lastElement, num)
X =
       0    0.1111    0.2222    0.3333    0.4444    0.5556    0.6667    0.7778    0.8889    1.0000
