and after RUN

Perhaps you are calling the function with two few arguments, such as this on the command line:
quadraticc(2)
If you are simply hitting the "Run" button, then the program assumes no inputs at all, and b happens to be the first one it comes across.
Neither of these are bugs in the code, simply incorrect usage. If you want to prevent this, define defaults:
function quadraticc(a,b,c)
arguments
a (1,1) double = 1
b (1,1) double = 0
c (1,1) double = 0
end

you aren't calculating r when k<0, but you still try to display it

Save the function in a folder...and :
a = 1 ;
b = 2 ;
c = 3 ; % define your variables
quadratic(a,b,c)
