collect multiple variable in one set

Hi everyone,

i have many classifiers and the user select some of them and after that i need to plot the roc for the selected classifiers. my problem is how to collect the names in the roc format. example :

the user may select these classifers

w4 = polyc(Training_Set);
w7 = treec(Training_Set);
w10=nmc(Tra ining_Set);

then i need to put the variable (w4,w7,w10) in this form:

 e= roc(Testing_set, {w4,w7,w10});
plote(e);

please can anyone help me ASAP

Best regard

You can create a structure to collect all the various variables into one variable:

allMyClassifiers.w4 = w4;
allMyClassifiers.w7 = w7;
allMyClassifiers.w10 = w10;

Or you can keep the classifier number totally independent of what's assigned to it.

allMyClassifiers.c1= w4;
allMyClassifiers.c2= w7;
allMyClassifiers.c3= w10;

Or you can create a cell array where each cell is one classifier. That way you just index the classifiers by a number that doesn't depend on the name of the classifier:

allMyClassifiers{1}= w4;
allMyClassifiers{2} = w7;
allMyClassifiers{3} = w10;

Then call your function passing it:

e = roc(Testing_set, allMyClassifiers);

thank you very much "Image Analyst", i use the third one which is a cell array and it work with me,

thank again,
