Specify data type for import data from csv by using readtable with different number of columns

Hello everybody,

i tried to import a .csv file with different number of columns. I used readtable. The only way to do so was to set the ExtraColumnsRule to 'addvars'. But that gives some entries with ExtraVar in my table, where I can not specify the data type. I would like to read them as double, but they are char by default and are not accessable...

can you give me a hint how to solv that?

I'm using Matlab 2017b, but delimitedTextImportOptions and fixedWidthImportOptions are not available...

I attached a file with testdata and the code.

Regards,

Christian
