ex: I have
x=0:0.3:1;
y=0:0.3:1;
meshgrid [x,y] ;
surf(x,y,u);
but i need u(0.567,0.111)

Prayag - in your above code example, you are trying to use u before it has been defined. As well, the input to meshgrid will likely generate an error too. What is your code trying to accomplish? How is u related to x and y?
