thanks for the quick reply.it works fine!

regarding the initialisation of  csv[][] as a  string array, i did it this way because there are also col & rows names that i want to print. I tried to initialise it as float array and print the name with Float.toString(float i) but didn`t work...so i stick to string array, if there is a different way, an indication would be more than welcome.. :)


but there is something regarding min () & max() that i do not fully understand.

i tried this

1.  float [] findIt=new float[data.length];
2.   float [] t=new float[2];
3.   for (int i=1; i<data.length; i++){
4.     findIt[i]=Float.parseFloat(csv[i][1]);
5.      //println(findIt[i]);  
6.     if (max(findIt) > 0){
7.       maxi=max(findIt);
8.      //t[0]=maxi;
9.     } if (min(findIt) < t[0]){
10.       mini=min(findIt);
11.     }
12. }    
13.   println(maxi);
14.   print(mini);
15. }

and it prints only the max value correctly and a zero value for the min()

i tried it in a different 2d array like this

1. int[][] myArray = {  {150, 517, 189,400},
2.                      {123,  80, 441, 250},
3.                      {500,  550, 149,  500},
4.                      {568, 346, 134,  80}  };
5. float [] findIt=new float [myArray.length];
6. float maxi;
7. float mini;
8. float [] t=new float [2];
9. void setup(){
10.   for (int i=0; i<4; i++){
11.     for (int j=0; j<4; j++){
12.     findIt[i]=myArray[i][0];
13.       if (max(findIt) > 0){
14.         maxi=max(findIt);
15.         t[0]=maxi;
16.       }if (min(findIt) <maxi) {
17.         mini=min(findIt);
18.         t[1]=mini;
19.       }
20.     }
21.   }
22.   //println(mini);
23.  // print(maxi);
24. println(t[0]);
25. print(t[1]);
26. }

and it works fine on both min() & max()

in what way are these two different?
