I'm a beginner in Matlab
Please could you help me with the following code:
I want to write a sequence s_n = 1/n where n=1,2...100 and plot the result.
I tried this, n=1
for i = 1:100
n= n+1
end
Sn= 1/n
But It only displays the last number for n=100 and divides
I have no idea how to do it and the results I found don't satisfy me.
Thank you

Use element-wise division:
n = 1:100;
format short
Seq = 1./n
producing:
Seq =
1.0000 0.5000 0.3333 0.2500 0.2000 0.1667 0.1429 0.1250 0.1111 ...
alternatively:
format rat
Seq = 1./n
producing:
Seq =
1 1/2 1/3 1/4 1/5 1/6 ...

Forgot to include the plot call.
Here it is:
figure
plot(Seq)
grid
This is the same as:
figure
plot((1:numel(Seq)), Seq)
grid
