Why does using a comma decimal separator only work for data with more than one column?

When using

readmatrix(filename,"DecimalSeparator",",")

on a TXT file with multiple columns such as below, it works as expected.

 

Before:

0,1 0,2

0,3 0,4

After:

0.1 0.2

0.3 0.4

When the data only has one column, however, the command does not produce the desired results.

Before:

0,1

0,3

After:

0 1

0 3

How can I use "readmatrix" for a one column TXT file with comma decimal separators?

In this case, it will be necessary to define the delimiter as an additional input argument:

readmatrix(filename,"DecimalSeparator",",","Delimiter"," ")
