textscan doesn't work well when I read 2 lines batch.

using code below I can't read third number of data I think encoding newline has problem. interestingly when I make test data by typing with same form it works well. but when I deal with raw data it doesn't work. what's the problem?

data :

842428 / Present Voltage = 229
 Present Velocity = 8973
842863 / Present Voltage = 228
 Present Velocity = 8997

code :

clc; clear; close all;
fid = fopen("23V, 0.17~0.20A.txt","r");
data = textscan(fid,'%d / Present Voltage = %d Present Velocity = %d');
fclose(fid);

result :

data = 842428, 229, []

Try this

str = sprintf( '842428 / Present Voltage = 229\n Present Velocity = 8973\n' );
str = [ str, str ];
data = textscan( str,'%d / Present Voltage = %d\n Present Velocity = %d\n')
data = 
    [2x1 int32]    [2x1 int32]    [2x1 int32]

Seems that you need to add newline code (\n) or carriage return + newline codes (\r\n), like:

data = textscan(fid,'%d / Present Voltage = %d\r\n Present Velocity = %d');

In my PC environment (Windows10 + MATLAB R2018a), it returns 1-by-3 cell array.

>> data
data =
1×3 cell array
  {2×1 int32}    {2×1 int32}    {2×1 int32}

Thank you so much! '\r' this was the problem!!
