importdata Load data from file.
 
    importdata(FILENAME) loads data from FILENAME into the workspace.
 
    A = importdata(FILENAME) loads data into A.
 
    importdata(FILENAME, DELIM) interprets DELIM as the column separator in
    ASCII file FILENAME. DELIM must be a character vector or string scalar.
    Use '\t' for tab.
 
    importdata(FILENAME, DELIM, NHEADERLINES) loads data from ASCII file
    FILENAME, reading numeric data starting from line NHEADERLINES+1.
 
    [A DELIM] = importdata(...) returns the detected delimiter character
    for the input ASCII file.
 
    [A DELIM NHEADERLINES] = importdata(...) returns the detected number of
    header lines in the input ASCII file.
 
    [...] = importdata('-pastespecial', ...) loads data from the system
    clipboard rather than from a file.
 
    Notes:
 
    If importdata recognizes the file extension, it calls the MATLAB helper
    function designed to import the associated file format.  Otherwise,
    importdata interprets the file as a delimited ASCII file.
 
    When the helper function returns more than one nonempty output,
    importdata combines the outputs into a structure array.  For details,
    type "doc importdata" at the command prompt.
 
    For ASCII files and spreadsheets, importdata expects to find numeric
    data in a rectangular form (that is, like a matrix).  Text headers can
    appear above or to the left of numeric data.  To import ASCII files
    with nonnumeric characters anywhere else, including columns of
    character data or formatted dates or times, use TEXTSCAN instead of
    importdata.  When importing spreadsheets with columns of nonnumeric
    data, importdata cannot always correctly interpret the column and row
    headers.
 
    Examples:
 
    1) Import and display an image:
 
         nebula_im = importdata('ngc6543a.jpg');
         image(nebula_im);
 
    2) Using a text editor, create an ASCII file called myfile.txt:
 
         Day1  Day2  Day3  Day4  Day5  Day6  Day7
         95.01 76.21 61.54 40.57  5.79 20.28  1.53
         23.11 45.65 79.19 93.55 35.29 19.87 74.68
         60.68  1.85 92.18 91.69 81.32 60.38 44.51
         48.60 82.14 73.82 41.03  0.99 27.22 93.18
         89.13 44.47 17.63 89.36 13.89 19.88 46.60
 
       Import the file, and view columns 3 and 5:
 
         M = importdata('myfile.txt', ' ', 1);
         for k = [3, 5]
             disp(M.colheaders{1, k})
             disp(M.data(:, k))
             disp(' ')
         end
