N=...;

sum = 0.0;

for k=1:N

sum = sum+1/k;

end

Iam new in this . So need a complete script please.

I don't see why the code you wrote wouldn't work.

N = 100;
s = 0; % using sum as a name shadows the function sum()
for k = 1:N
    s = s + 1/k;
end
s
s = 5.1874

That works, but you can always do it without the loop.

s = sum(1./(1:N))
s = 5.1874

It is showing an error

Undefined function or method 'summation' for input arguments of type 'char'.

(summation is my file name) This is the error

Attach your file and an example of how you're calling it.

Is summation.m a function or a script? If it's what you posted already, it's a script and should not give any error about inputs since there are no inputs. And it should work, once you rename sum to x, as DGM showed in his answer, which ran it in MATLAB online.

On the other hand, if it's a function the first line will be

function summation(N)

and maybe you're supposed to call it passing in N and maybe all you did was click the green run triangle without assigning N. Again, attach your m-file. Use the paperclip icon.
