MATLAB: Reading a text file without headers

readingtext filewithout headers

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.
