Hi,
Variable a and b tends to be constants. Equation of ellipsoid as in your (a) part of the question is as follows:
x^2/a^2 + y^2/b^2 + z^2/c^2 = 1 .
Following code may help:
clc
close all
clear
a=1;
cb=2;
l=-3.14:0.1:3.14; %lemda
b=-3.14/2:0.1:3.14/2;
[X,Y]=meshgrid(l,b);
x=a.*cos(X).*cos(Y);
y=a.*sin(X).*cos(Y);
z=cb.*sin(Y);
r=surf(x,y,z);
Output:
Similarly other parts of the question can be solved.
