MATLAB: How to save data from features files into matrix

image processing

i want to save data from 500 images features files every file contain 6 types of features types such as jcd,tamura,….. .,
the problem is that the data for these 6 features are seperated by comma,i want to make six matrices for these 500 image for type of features ,i atteched this file to help
can any one help

Best Answer

I understand that "data for each feature for 500 images" is in ONE text file with 500 blocks of six rows. The format is illustrated by im1.txt which contains two blocks.
Try this 
>> S = cssm('im1.txt')
S = 
  1×2 struct array with fields:
    JCD
    Tamura
    ColorLayout
    EdgeHistogram
    AutoColorCorrelogram
    PHOG
>> JCD_matrix = cat( 1, S(:).JCD );
>> whos JCD_matrix
  Name            Size             Bytes  Class     Attributes
  JCD_matrix      2x168             2688  double
where (in one m-file)
function    im = cssm( ffs )
    %%
    fid = fopen( ffs, 'rt' );
    buf = textscan( fid, '%s', 'Delimiter', '\n' );
    fclose( fid );
    buf = buf{1};
    %%
    len = floor( size(buf,1)/6 );     % number of blocks
    im(1,len) = struct( 'JCD',[], 'Tamura',[], 'ColorLayout',[]                 ...
            ,   'EdgeHistogram',[], 'AutoColorCorrelogram',[], 'PHOG',[] );
    %%
    for jj = 1 : len
        im(jj).JCD                  = read( buf{(jj-1)*6 + 1 }, 'JCD'                 , (jj-1)*6+1 );
        im(jj).Tamura               = read( buf{(jj-1)*6 + 2 }, 'Tamura'              , (jj-1)*6+2 );
        im(jj).ColorLayout          = read( buf{(jj-1)*6 + 3 }, 'ColorLayout'         , (jj-1)*6+3 );
        im(jj).EdgeHistogram        = read( buf{(jj-1)*6 + 4 }, 'EdgeHistogram'       , (jj-1)*6+4 );
        im(jj).AutoColorCorrelogram = read( buf{(jj-1)*6 + 5 }, 'AutoColorCorrelogram', (jj-1)*6+5 );
        im(jj).PHOG                 = read( buf{(jj-1)*6 + 6 }, 'PHOG'                , (jj-1)*6+6 );
    end
end
function    row = read( chr, name, n )
    cac = strsplit( chr, ':' );
    assert( strcmp(cac{1},name),'Row, %d, is "%s". Expected is "%s"', n, cac{1}, name )
    num = textscan( cac{2}, '%f', 'Delimiter',',' );
    row = reshape( num{1}, 1,[] );
end
If execution time is a problem replace
cac = strsplit( chr, ':' );
by
cac = regexp( chr, ':', 'split' );
