MATLAB: Calculating a function and drawing a graph

MATLABsymbolic

derivative at x=1 and drawing a function graph.

my solution was:

but didnt work. Need help.

x= 1;

f(x) =sin*x/x^2+1;

fplot(f)

Best Answer

syms x
f=sin(x)/(x^2+1);
fplot(f)       
derivative=diff(f,x)
derivative_when_x_equals_one=double(subs(derivative,x,1))

Use syms x and use fplot() to plot the function

MATLAB: Calculating energy

In order to obtain energy, do not even worry about the power. Just do this:

Using "*y*" and "*f*" from the output of spectrogram -

N = 250; % window length
Fs = 500; % sample frequency
df = Fs/N; % frequency increment
y_squared = (y/Fs)*conj(y/Fs);  % Fs is used to normalize the FFT amplitudes
energy_10Hz_to_90Hz = 2*sum(y_squared( f>=10 & f<=90,: ))*df;

If at any point the range of frequencies you want to calculate the energy over includes either 0Hz or the Nyquist frequency, then you will not be multiplying those amplitudes by 2. Otherwise the above should work. You need to multiply the sum of squared amplitudes by the frequency increment (df) as I do above because you are essentially performing discrete integration across the interval between 10Hz and 90Hz.
