Count characters per row

Hey Guys,

I want to read and modify a txt.-file via MatLab and store the resulting data.

What I would like to do is to only keep the lines of the file which contain more than 100 characters and discard all the other lines/rows.

Thanks for the help!

How is text file? What data text file has?

[trst111]

The text file consists of 6 columns of data/text (columns are separated via spaces) and a huge amount of rows. I want to put everything into a matrix, except all the rows whose character count is less than 100.

Each rows has six columns....so what is a single element? It is a string right?

Attach some part of your file here. Or copy paste few lines.

[trst111]

Its built like this:

Value1 Value2 Value3 Value4 Value5 Value6

Value7 Value8 Value9 Value10 Value11 Value12

Value13 Value14 Value15 Value16 Value17 Value18

...

the values are looking like this: -6.314264449E-002

Trivial if you read your file to a cell array (e.g. with readfile, which you can get from the FEX or through the AddOn-manager (R2017a or later)).

L=false(numel(data));
for n=1:numel(data)
    L(n)=numel(data{n})<100;
end
data(L)=[];
