I have a vector that contain number of class
numberclass=[50,100,250,500,1000]
I want to plot the variation of result between 3 feature : the accuracy of the feature1 is :
Accuracy1=[94,90,88,79,77]
the accuracy of the feature2 is :
Accuracy2=[90,80,79,75,71]
the accuracy of the feature3 is :
Accuracy3=[98,90,85,70,60]

Use the hold function to put multiple plots on the same set of axes:
numberclass=[50,100,250,500,1000];
Accuracy1=[94,90,88,79,77];
Accuracy2=[90,80,79,75,71];
Accuracy3=[98,90,85,70,60];
figure(1)
plot(numberclass, Accuracy1)
hold on
plot(numberclass, Accuracy2)
plot(numberclass, Accuracy3)
hold off
grid
xlabel('Number of selected classes')
ylabel('Classification Accuracy')

My pleasure.
The documentation for the plot and legend functions have all the information you need to make a plot like the one you provided in your Question. Anything I would provide here would simply be restating what is already in the documentation.
