Consider the execution of the following MATLAB code:
a = 11;
b = 4;
z = 5:5:25;
for k = a:-1:b
if k > 5
z = z - 5; %
elseif k == 3
z = z - 10; %
else
z = z - 4; %
end
end %
% Which is the loop index variable?

k is the loop index variable in the code that you showed. The loop index variable is always defined after for:
for ??? = ...
^ this is where the loop index available is specified.
This is also shown in the MATLAB documentation:
