Hello I am trying to do the following computation confusionmat
h = 5.1000 3.5000 1.4000 0.2000
6.4000 3.2000 4.5000 1.5000
5.4000 3.4000 1.7000 0.2000
5.7000 2.8000 4.5000 1.3000
5.7000 4.4000 1.5000 0.4000
5.6000 2.9000 3.6000 1.3000
k = 5.1000 3.8000 1.9000 0.4000
6.4000 2.9000 4.3000 1.3000
4.3000 3.0000 1.1000 0.1000
5.4000 3.0000 4.5000 1.5000
0 0 0 0
0 0 0 0
C = confusionmat(h,k);
I got the following errors below
Error using confusionmat (line 86)
First two arguments must be vectors or character matrices.
Error in zondo (line 166)
C = confusionmat(Training,Test1);

Please read the error message: The first two inputs must be numerical vectors. The documentation explains the allowed inputs exhaustively:
doc confusionmat
It is impossible to give you an advice how to implement, what you actually want to compute, because you do not mention the purpose of the code.
