When calling importdata on a csv file with empty fields, octave groups them
all in a single column:

this csv "myfile.csv"


title;casename;0
;;
load case;;
height;h;1.3


with this call


A=importdata("myfile.csv")


produces this output


A =
{
  [1,1] = title;casename;test;0
  [2,1] = ;;;
  [3,1] = load case;;;
  [4,1] = height;h;m;1.3
}


while matlab produces this output


A =

  scalar structure containing the fields:

    data =

            0
           NA
           NA
       1.3000

    textdata =
    {
      [1,1] = title
      [2,1] = 
      [3,1] = load case
      [4,1] = height
      [1,2] = casename
      [2,2] = 
      [3,2] = 
      [4,2] = h
    }


which I would also expect from octave
