Can you please solve this problem on MATLAB please make sure

Can you please solve this problem on MATLAB. please make sure to give me an error for imaginary number. Thanks a lot

Solution

%matlab code here

function [ x1,x2 ] = froot( a,b,c )
%FROOT Summary of this function goes here
% Detailed explanation goes here
h=b^2-4*a*c;

if h<0
error(\'roots are imaginary\');
abort;
else
x1=(-b+sqrt(h))/(2*a);
x2=(-b-sqrt(h))/(2*a);
end

end

---------------------------------

>> froot(1,-1,12)
Error using froot (line 7)
roots are imaginary

--------------------------------

>> [x1 x2]=froot(4,13,-17)

x1 =

1

x2 =

-4.2500

-----------------------------------------

>> [x1 x2]=froot(2,-4,2)

x1 =

1

x2 =

1
