Hello,
I am trying to use parfor to plot some filled rectangles with the following codes for some data x,y,f and a parameter l, this code works fine on serial for loop, when I tried to do it with parfor, it returns an empty figure, how should I resolve this? Thank you!
figure();
for i = 1:length(f)
if f(i)==1
fill( [x(i) x(i)+l x(i)+l x(i)],...
[y(i) y(i) y(i)+l y(i)+l],[0 91 187]/255,'LineStyle','none');hold on;
end
end

" Btw, why is l a bad variable name"
- l looks like 1. When a human is reading your code, it's very easy to misinterpret y(i)+l as adding 1
- Single character variable names are often used in loops (for i = 1:10) and to represent common variables such as p-values (p = anova1(...)) but in general, it's best to use variable names with more than 1 character.
- When using the editor, if you select a variable you'll notice that all instances of that variable within the same function are highlighted. With a variable name as narrow as l you lose the ability to quickly see all of those instances.
- It's very easy to accidentally type a single-character variable name via a typo. It's much more difficult to accidentally type LValue than l.
