Logical indexing for two conditions

Hi I have this code:
Excess=zeros(size(Energy));
for i=1:length(Energy)
if Energy(i)>= 20
Excess(i)=Energy(i)-20;
end
end
I would like to replace the for loop using logical indexing. I would appreciate any help.
Best Regards,
Ritika

Excess = zeros(size(Energy));
m = (Energy >= 20);
Excess(m) = Energy(m) - 20;
A simpler code, but without the wanted logical indexing:
Excess = max(0, Energy - 20);

Of course you can read the documentation of this command:
help max
doc max
Searching in the internet for "Matlab max" displays the online help: https://www.mathworks.com/help/matlab/ref/max.html
Matlab's documentation is very useful and much better than other manuals e.g. the help sections of Windows :-)
If a command does not do exactly, what you need, look at the "See also" line at the bottom, which suggests similar commands.
