Question

In Matlab:

Consider the multi-variable function given by:

allow the user to input scalar values for x, y, and z and include logic that will stop the script and display an error message if the function is singular or would result in an imaginary number for a provided set of x,y,z. If the function is allowed to evaluate, display the entered values of x,y, and z as well as the value of the function using a single instruction. ?Otherwise, display an error message. Evaluate at the following points (x,y,z):

i.     (4,13,15)

ii.    (8,-12,0.1)

iii.    (0,0,0)

iv.    (5,10,15)

Explanation / Answer

x = input('Enter x: ');
y = input('Enter y: ');
z = input('Enter z: ');

if x + y + z == 0
   disp('Undefined value of function');
elseif 5 * z * z + x * y * y * y < 0
   disp('Imaginary value of function');
else
   disp(((36 * x * y) + sqrt(5 * z * z + x * y * y * y)) / (x + y + z));
end
