i wanna classify dataset based on multiple criterion. nested if else statements will get me the results but i would like use more efficient and elegant method (something like supervised learning method).
for example
p range p1 range p2 range output
0 to -1 0 to 1 < 50 class 1
p range p1 range p2 range output
0 to -1 0 to 1 50 to 100 class 2
p range p1 range p2 range output
0 to -1 0 to 1 >100 class 3
p range p1 range p2 range output
0.1 to 1 -0.1 to -1 < 50 class 4
p range p1 range p2 range output
0.1 to 1 -0.1 to -1 50 to 100 class 5
p range p1 range p2 range output
0.1 to 1 -0.1 to -1 > 100 class 6
I tried classification learner app but couldn't achieve the results. kindly help me.

If those are your known criteria, then you don't need any fancy classification code or functions, simple use a series of if/else statements:
if p > -1 && p < 0 && p1 > 0 && p1 < 1 && p2 < 50
theClass = 1;
elseif p > -1 && p < 0 && p1 > 0 && p1 < 1 && p2 > 50 && p2 < 100
theClass = 2;
etc.
