I want to open this text file and read the first field (before the semi column) as string and store them in the string array.

The next four numbers will be stored them in array of 4 column floating number.

Array A is a string array, array B is a floating number array

A = 20120906092900   B = 55.05 87.82 87.82 84.28
    20120906093000       55.05 87.81 87.81 84.28
    20120906093100       55.05 87.82;87.82;84.29
    20120906093200       55.04 87.82 87.82 84.29
    20120906093300       55.04 87.81 87.81 84.28
    20120906093400       55.04 87.82 87.82 84.28
    20120906093900       55.03 87.81 87.81 84.27
    20120906094000       55.02 87.81 87.81 84.28
    20120906094100       55.02 87.81 87.81 84.29
    20120906094200       55.02 87.81 87.81 84.29
    20120906094300       55.01 87.82 87.82 84.28
    20120906094700       55.00 87.81 87.81 84.28
    20120906094800       55.00 87.82 87.82 84.29

Like this?

fid = fopen('YourData.txt','r');
C = textscan(fid,'%s%f%f%f%f%*4s','Delimiter',';');
fclose(fid);

A = string(C{1});
B = cell2mat(C(2:end));
