I need to read a file with rows like this

calculation.update.date=09.10.2019¶

I'm textscanning the ".txt" into 2 column matrix (one with "calculation.update.date" and the other one with "09.10.2019¶")

To do that I used

opt = {'Delimiter','='};

data_type = '%s%[^\n]';

fileID = fopen('ENTRADA.txt','rt');

C_aux = textscan(fileID,data_type,opt{:},'CollectOutput',1);

I would like to do the same but getting "09.10.2019" in the second column instead of "09.10.2019¶"

I would also like to be able to include a ¶ at the end of each row when finishing the program, in order to export it in a proper way.

How could I do it?

Thanks in advanced!

Sergio

在 MATLAB Online 中打开

This should help:

>> A = '09.10.2019¶'
A =
    '09.10.2019¶'
>> A(end) = []
A =
    '09.10.2019'

also maybe helpful:

>> a = '¶'
a =
    '¶'
>> double(a)
ans =
   182

also note:

>> A = "09.10.2019¶"  % String instead of char!
A = 
    "09.10.2019¶"
>> whos A
  Name      Size            Bytes  Class     Attributes
  A         1x1               166  string  
    
>> A(end) = []  % This doesnt work!
A = 
  1×0 empty string array  
>> A = char(A)
A =
    '09.10.2019¶'
>> whos A
  Name      Size            Bytes  Class    Attributes
  A         1x11               22  char               
>> A(end) = []
A =
    '09.10.2019'
