Function returns ans, how to exclude?

Good evening,

I am trying to write a script that returns 2 answer for the quadratic equation.

And I want to be able to input whatever values for a,b,c I want.

I have written this in the script:

function [x1,x2] = quad_equation(a,b,c)
prompt = 'a = ';
a = input(prompt);
prompt2 = 'b = ';
b = input(prompt2);
prompt3 = 'c = ';
c = input(prompt3);
x1=(-b+sqrt(b.^2-4.*a.*c))/(2.*a)
x2=(-b-sqrt(b.^2-4.*a.*c))/(2.*a)
end

It runs fine, but it outputs with "ans" at the end, and I can't figure out how to get rid of it.

Output:

x1 =

1

x2 =

-4

ans =

1

Any suggestions? :)

What is the point in defining a fucntion with three input arguments, which are then totally ignored?

function [x1,x2] = quad_equation(a,b,c)
prompt = 'a = ';
a = input(prompt);
prompt2 = 'b = ';
b = input(prompt2);
prompt3 = 'c = ';
c = input(prompt3);

Get rid of all of those input calls, input makes functions untestable, unrepeatable, ungeneralizable, unexpandable.

Change

x1=(-b+sqrt(b.^2-4.*a.*c))/(2.*a)
x2=(-b-sqrt(b.^2-4.*a.*c))/(2.*a)

to

x1=(-b+sqrt(b.^2-4.*a.*c))/(2.*a);
x2=(-b-sqrt(b.^2-4.*a.*c))/(2.*a);

Then, when you run your function, be sure to assign the results to variables, and be sure to put a semi-colon at the end of the line:

[first, second] = quad_equation(83,-5,-9);

Answer 2

[madhan ravi]

 [x1, x2] = quad_equation

 function [x1, x2] = quad_equation
 prompt = 'a = ';
 a = input(prompt);
 prompt2 = 'b = ';
 b = input(prompt2);
 prompt3 = 'c = ';
 c = input(prompt3);
 x1=(-b+sqrt(b.^2-4.*a.*c))/(2.*a);
x2=(-b-sqrt(b.^2-4.*a.*c))/(2.*a);
 end
