Reading a text file without headers

4 次查看(过去 30 天)
Hi,
I have a text file without headers and starting as shown below with spacing. I have 3652500 rows in the text file. How can I read this text file using MATLAB.
1 1 1 1 0.00 55. 36. 295.
Thanks in advance,

If all rows have the same number of columns
dlmread, Read ASCII-delimited file of numeric data into matrix
Syntax
M = dlmread(filename)
M = dlmread(filename, delimiter)
M = dlmread(filename, delimiter, R,C)
M = dlmread(filename, delimiter, range)
.
Example in response to comment:
This works fine here (R2013a)
filespec = 'h:\m\cssm\sample\sample.txt';
num = dlmread( filespec );
whos num
returns
Name Size Bytes Class Attributes
num 20x8 1280 double
Doc says
When dlmread infers the delimiter from the formatting of the file, it
treats repeated white spaces as a single delimiter. By contrast, if you
specify a delimiter, dlmread treats any repeated delimiter character as
a separate delimiter.

I tried this code
M = dlmread('OUTPUT.txt', '\t');
I am getting this error
Error using dlmread (line 141) Mismatch between file and format string. Trouble reading number from file (row 1u, field 1u) ==> @BCDE
Anybody have an idea.?

See the example, which I added to the answer.
sample.zip, which you attached, contains a file named sample.txt. This file is not tab delimited, but space delimited.
I failed to reproduce your error.
