I am trying to use a MATLAB function to generate a plot for the function :

As such I am using the linspace function to generate an input array that I then aim to give to the function i wrote to get data to be plotted. But the function only processes the first element of the Array generated by linspace. The function appears to work correctly for singular values but not for arrays.

function S = FXSUM(x) 
Tot = 0; % reset Total
for n = 2:x % for loop for Function Summs at a iterations
it = (1/(n*((log(n))^2))); % provided function
Tot = Tot + it % sum of function iterations
end
S = Tot; % Out value equal to function iterrations total
end

Your function is not written to accept a vector as input. You likely need to add a second loop to run for each element of your input vector.

Right now, it creates your loop counter using 2 and the first element of

x = 5:8
x = 1×4
5 6 7 8
