I am trying to plot f(x)=ln(1-x)/x for -10^(-15)<=x<=10^(-15) but when I run the program it says "Unable to perform assignment because the size of the left side is 1-by-1 and the size of the right side is 1-by-300." How can I alter my code so that it properly plots the function?
My code:
x = linspace(-10^(-15),10^(-15),300);
f = zeros(1,300);
for i = 1:300
f(:,i) = log((1-x(:,i))) ./ x;
end
f;
figure;
plot(x,f);

Ran in:
x = linspace(-10^(-15),10^(-15),300);
f = log(1-x)./x;
plot(x,f)
