MATLAB: How to solve this integration ???

This shows that MATLAB is not able to find a closed-form expression for the integration problem. You can still find the numerical answer by substituting the numeric values of a and b

syms x a b
c = (x*cos(x)*sin(x))/(a^2*cos(x)^2 + b^2*sin(x)^2)^2;
c_int = int(c, x, 0, pi/1);
x = subs(c_int, [a b], [1 2]);

This will give the value of integration at a=1, b=2. Result:

>> x
x =
-pi/12

MATLAB: Array and inverse tan

I think you do not unerstand MATLAB. I'd start with taking the Onramp tutorial. atand of what?

atand is a FUNCTION. You need to pass it arguments. For example, Perhps you intended to write this:

phata_values = atand(phataY./phataX);

Or perhaps you wanted to write

phata_values = atand(z).*(phataY./phataX);

where z is some unknown variable that you never told us about.
