I'm new to matlab and I want to create a loop where I re use the previous calculate value in the next iterations.
This is what I have right now but I have up until thirtyPerc so instead of writing it out I would like to create a for loop instead.
StartTime = Time(1,1);
OnePerc = StartTime + (PercentageTimeLeft * 10);
twoPerc = OnePerc + (PercentageTimeLeft * 10);
threePerc = twoPerc + (PercentageTimeLeft * 10);
PercentageIntervalTimes = [OnePerc,twoPerc,threePerc];
This is what I tried to do:
PercentageIntervalTimes = [];
OnePerc = StartTime + (PercentageTimeLeft * 10);
for i = 1:length(Time)
PercentageIntervalTimes = OnePerc (i +1 ) + (PercentageTimeLeft * 10);
end
Any help is very much appreciated!
Thanks!!

PercentageIntervalTimes = StartTime + (1:length(Time))*(PercentageTimeLeft * 10);
No loop needed.

Hi @Iris Willaert,
This is something that you can do.
PercentageIntervalTimes = zeros(length(Time));
PercentageIntervalTimes(1) = StartTime + (PercentageTimeLeft * 10);
for i = 2:length(Time)
PercentageIntervalTimes(i) = PercentageIntervalTimes(i-1) + (PercentageTimeLeft * 10);
end
Kindly ensure that Time is an array-like data type.
