For Loop How to use previous calculated value in next iteration

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!!

Answer 1

[Torsten]

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.
