Error using == (line 25)

Invalid types for comparison.

Error in confusion (line 45)

if ~all((targets==0) | (targets==1) | isnan(targets))

Error in Bysian_rule (line 3)

[c,cm,ind,per] = confusion(Group_Test1,labelIdx);

knowing that:

Group_Test    788x1 categorical
labelIdx.mat  788x1 categorical

Hello,

Without having your function 'confusion.m', or at least the concerned lines, it can be difficult to help.

But I think the error says that you can't compare a categorical value (targets) with a boolean (1 or 0).

Maybe convert target into logical first, like this

targets = logical(targets);

Let me know if it worked.

Regards,
