Re: How to compare the colums ( 2nd and 3rd) of 2 .csv files based on a condition

[Ganesh Kini]

Rather than hardcore it, like   >> pos_a_1 = (condition1(:,2)=='a')

how can i make it in general? Do I need to use for loop? Please let me know how to do it ?

So for the answer of data1 

data1 = textscan (file1, "%s,%f,%f,%d \n" , "HeaderLines" , 1, "Delimiter" , "," )

>> data1
data1 =
{
  [1,1] =
  {
    [1,1] = tb
    [2,1] = tb
    [3,1] = tb
    [4,1] = ta
    [5,1] = ta
    [6,1] = tc
    [7,1] = tc
    [8,1] = tc
  }

  [1,2] =

     1.070000
     0.070000
     1.170000
     1.270000
     1.370000

     1.470000
     1.470000
     1.670000

  [1,3] =

    -1.1100
    -1.2300
    -1.6700
    -1.5700
    -1.3700
    -1.0700
    -1.4700
    -3.9700

  [1,4] =

    1
    2
    3
    1
    2
    1
    2
    3

}
