I am not sure exactly what you are asking.

If you are asking that the above be automatically be read into
a 4x4 array, the answer is no.

More generally, I think you are asking that an ascii file with arbitrary
column [C] and row [R] elements and an irregular structure automatically be
read into a RxC array. Sorry, no.

ncl 1> x = asciiread("ozan.asc", -1, "float")
ncl 2> print(x)

Variable: x
Type: float
Total Size: 32 bytes
             8 values
Number of Dimensions: 1
Dimensions and sizes: [8]
Coordinates:
(0) 0.1
(1) 0.2
(2) 0.4
(3) 0.1
(4) 2.3
(5) 2.7
(6) 2
(7) 1.1

good luck
