Hi all, I am working on radar receiver to test its performance via ROC curve. ROC curve is between SNR ( signal to noise ratio) and Pd(probability of detection) at given Pfa(Probability of false alarm). I need to plot these curves with "probplot"(SNR - x-axis) and Pd( y-axis). Moreover, I need all plots in one curve.(hold on didn't work). any suggestion?. Thank you in advance.

You can use a syntax similar to the following lines of code to plot more than one 'probplot' in one graph:

x1 = wblrnd(3,3,100,1);
x2 = raylrnd(3,100,1);
x3 = raylrnd(3,100,1);
probplot('weibull',[x1 x2 x3])

Dear Vishal,

I just what to ask on how to plot linear probablity plot as the picture shown. you used random numbers in your code, but what if there is a x and y values?

for example.

x=[ 44 38 36 35 27 26.5 26 26 24 23.5 23 23 21 20.5 19.5 19 19 19 19 19 18 18 17.6 17 17 17 16 16 16 16 14.5 14 13 11 11 10 9 8.5 ]

y = [ 0.974359 0.974359 0.974359 0.974359 0.974359 0.974359 0.974359 0.974359 0.974359 0.974359 0.974359 0.974359 0.974359 0.974359 0.974359 0.974359 0.974359 0.974359 0.974359 0.974359 0.974359 0.974359 0.974359 0.974359 0.974359 0.974359 0.974359 0.974359 0.974359 0.974359 0.974359 0.974359 0.974359 0.974359 0.974359 0.974359 0.974359 0.974359 ]
