i have to create a grid using meshgrid fn. and name it as grid_mat. i'm unable to name it and select points on it for different planets .

Create a grid using the function meshgrid (x, y), where x and y are coordinates of points in the solar system. Name this grid as grid_mat. By choosing the origin of the grid to be the Earth, specify the coordinates of Moon and Mars. Make sure that the Moon is between Earth and Mars. Assume the orbits of Moon and Mars to be circular.
% this is what i did
x = -8:8 ;
y = -8:8 ;
[X,Y] = meshgrid(x,y) ;
%Y = m.^2 - 4
a = b = 0;
grid_mat = sqrt((X-a).^2 + (Y-b).^2) ; %distance from any point a,b
Z = f(X,Y)
%G = 6.67428*10^(-11) ;
surf(X,Y,Z)

You can't assing variables that way
a = b = 0;
You can use deal
[a,b] = deal(0);
Or you can separately initiate variables
a = 0;
b = 0;
