MATLAB: How to plot position vs time

plottingposition;

How do I create a script that will plot the vectors of time values(t) and position values(x) at the same time where as the relationship between time and position is that position is equal to the natural log of time. All help is greatly appreciated.

Thanks again

t = 0:1000; % Your time vector
x = log(t); % Position is natural log of time
plot(t,x)   % Plot your data

Try this:

% Plot FFT signal
N = pow2(nextpow2(length(signal)));
y = fft(signal,N)/length(signal);
Fn = Fs/2;
Fv = linspace(0, 1, fix(length(y)/2)+1)*Fn;
Iv = 1:length(Fv);
plot(Fv,abs(y(Iv))*2);
title('FFT');
xlabel('Frequency [Hertz]');
ylabel('Magnitude');

NOTE — I have not tested this. It should work.

MATLAB: X(t)=log(8)[t+Π(t)], t=[1e-4, 10]

% Vector to define t
t = [1e-4:0.001:10];
% product of all time instances
prod_t = prod(t);
% x(t)
x = log(8)*(t+prod_t);
% Plot t on x axis and x(t) on y axis
plot(t,x);
