See Delimited or formatted I/O to text files
.
Interactively:
I think the simplest way is to read the file interactively with "Import Data ..." in the File menu (R2012a).
.
Width code:
    fid = fopen('cssm.txt', 'r' );
    cac = textscan( fid, '%f%f%f%f%f%f', 'CollectOutput', true, 'Headerlines', 2 );
    fclose( fid );
    cac{:}
returns
    ans =
       1.0e-03 *
             0         0         0         0         0         0
             0         0         0         0         0         0
        1.0000         0    1.0000         0    1.0000         0
        1.0000         0    1.0000         0    1.0000         0
        1.0000         0    1.0000         0    1.0000         0
where cssm.txt contains
    XY          
      COP x    COP y    COP z
    0  0  0  0  0  0
    0  0  0  0  0  0
    0.001  0  0.001  0  0.001  0
    0.001  0  0.001  0  0.001  0
    0.001  0  0.001  0  0.001  0
.
Including the header:
    fid = fopen('cssm.txt', 'r' );
    h1  = textscan( fid, '%s', 1 );
    h2  = textscan( fid, '%s%s%s%s%s%s', 1, 'CollectOutput', true );
    cac = textscan( fid, '%f%f%f%f%f%f', 'CollectOutput', true, 'Headerlines', 0 );
    fclose( fid );
    h1{:}
    h2{:}
    cac{:}
returns
    ans = 
        'XY'
    ans = 
        'COP'    'x'    'COP'    'y'    'COP'    'z'
    ans =
       1.0e-03 *
             0         0         0         0         0         0
             0         0         0         0         0         0
        1.0000         0    1.0000         0    1.0000         0
        1.0000         0    1.0000         0    1.0000         0
        1.0000         0    1.0000         0    1.0000         0

Mimicing xlsread output
    fid = fopen('forceplate_3.txt', 'r' );
    h1  = fgetl( fid );
    h2  = textscan( fid, '%s%s%s%s%s%s', 1, 'CollectOutput', true );
    cac = textscan( fid, '%f%f%f%f%f%f', 'CollectOutput', true, 'Headerlines', 0 );
    fclose( fid );
    txtdata     = repmat({''}, 2, 6 );
    txtdata(1,1)= {h1};
    txtdata(2,:)= h2{:};
    numdata     = cac{:};
the results are:
    >> whos *data
      Name             Size              Bytes  Class     Attributes
      numdata      21000x6             1008000  double              
      txtdata          2x6                1382  cell
