Hello everyone,
I need to generate a grid from contourf function (I need the coordinates of the grid lines and the center of each cell, later I will perform the integral on this grid).
Does anyone know how can I obtain these values? Any help is appreciated.
X_s = readmatrix('Xs.xlsx');
Y_s = readmatrix('Ys.xlsx');
Z_s = readmatrix('Zs.xlsx');
R_s=sqrt(X_s.^2+Y_s.^2+Z_s.^2);
Phi_s=atan2(Y_s,X_s);
figure()
contourf(X_s,Y_s,R_s,20,'r','Linewidth',2)
axis equal
xlabel('X_s')
ylabel('Y_s')
colorbar
hold on
contour(X_s,Y_s,rad2deg(Phi_s),20,'k','Linewidth',1)

How can i define a range from my matrices and keeping a shape of the object in the same time? In this problem the spacing is not uniform.

From my understanding you want to generate a grid from contourf function, you can refere meshgrid and contourf.
