Here is the code:
C=0.3+0.5i;
V = linspace(-2.0,2.0,400);
[Re,Im] = meshgrid(V);
Z = Re + i * Im;
B = 0;
for K = 1:100
B = B+(abs(Z)<=2);
Z = Z.*Z + C;
end;
imagesc(B);
colormap(jet);
axis equal
In 2018a, the result is:
But, in 2015b, the result is:
Why this will happen? How can I get the second figure in 2018a version? Thank you very much.

Fractal in R2016b, R2017b, R2018a, R2018b, R2019a on Mac
Do you just happen to have an AMD cpu?

In release R2018a did you assign a value to the variable i before running that code? When you want to ensure that you're using the square root of -1 you should always use 1i. Try replacing your line:
Z = Re + i * Im;
with
Z = Re + 1i * Im;

etc.
