Hello everyone
I want to plot this expression of probability in matlab y=exp(-(K-1)) in function of P[dB]. How can I do it? Please i need help.
I tried with this code but it doesn't go.
function y = Swb(K,p)
K=4;
y= exp(-(K-1));
end

You need to use the plot() function.

Where does he say he wants the PSD? If he did, then yes, he'd use pwelch(). But I see him saying "I want to plot this expression...." and for that you'd use plot(). Of course his expression is just a single number since y = exp(-(K-1)) = exp(-(4-1)) = exp(-3) = 0.04978706.

If K is just a single number, like 4, then exp(-(K-1)) is just exp(-3), which is just 0.0497870683678639, not a whole curve. What would you have as the x coordinate?
