Read the whole file and do the selection in memory...if you read into table and create an auxiliary variable based on the existence of the matching string for the three classes as a categorical variable, then the grouping and conversion becomes trivial via

findgroups
splitapply

and/or

varfun

Didn't understand, i've already done something like that for the first function, but i don't think it's correct.

Are the number of lines always fixed? Or it will change?

I misunderstood the initial Q? thinking you had the two columns and just needed to split; not to build the RH column. For the latter, store the base text lines in a lookup table and then have to read the input file knowing it's composition. You can again read that full file into memory (cell array) and walk through it rather than reading record-by-record or you can read the counted number of records after reading the various counts; your choice.
