while loop for series

im suppose to evaluate the series y=1/m where m is 1 to 5

I can find the different values for y using a while loop statment but cant get it to sum all the values

here is my code so far

clear

m=0

while (m<5)

m=m+1

r=1/m

y=sum(r)

end

what am i doing wrong?

"what am i doing wrong?"

You are not actually adding anything to y on each iteration, instead you completely overwrite y with a new value, thus making your loop totally superfluous (because you only return the value of the last iteration). In any case a loop is not required:

https://www.mathworks.com/help/matlab/matlab_prog/vectorization.html

This is the simple MATLAB way (no loop):

>> m = 1:5;
>> y = sum(1./m)
y =  2.2833

A pointlessly complex looped way:

>> y = 0;
>> for k = m, y = y+1./k; end
>> y
y =  2.2833

Of course you could make that loop even more complex using while.
