Hello everyone,
I am new to MATLAB programming and I want to use a for loop starting with an index 5 and reducing to 1
Example in C++ I can write for int i = 5;i<=1;i--)
how can this be implemented in MATLAB

y = zeros(1,12);
for i = 1:12
y(i+1) = y(i) + ((5 - (4/50)*y(i)));
end
y
x = zeros(1,10);
for i = 10:-1:2
x(i-1) = x(i) + ((5 + (4/50)*x(i)));
end
x
Good Day,
May I ask how can I insert the start and stop variable on above code? for example I want to start in 17 to 30 or 15 to 2 with decrementing step.
Thanks and Regards,
Dennis
