How to plot the precision and recall curve?

The precision and recall values are calculated as per theand from these values how to get the precision and recall curve.

Recall=[ 0.0432    0.0789    0.1089    0.1365    0.1629    0.1875 0.2121    0.2348    0.2554    0.2743]
Precision=[0.4320    0.3945    0.3630    0.3413    0.3258    0.3125 0.3030    0.2935    0.2838    0.2743]

Whether the values obtained here are correct.

All the precision and recall curves starts and ends by one.

I don't really understand what you are asking, but if you want to plot these numbers then simply

plot( Recall, Precision )

will do the job.

(With the usual caveat that I would always explicitly create an axes first and explicitly pass that to the plot function).

[Pramod Soni]

Precision = [.........];

Recall = [.........];

[Where values are given by you in Precision and Recall]

cftool(Recall, Precision)

It will draw the actual graph
