Here i am sharing one of my data which are in .dat file. I have 16162 different files. I merged all into one file and want to read it in matlab and need to extract three parameter's values from a single file and arrange them in either row wise or column wise. I can do it by using C sharp codes but i want to do it by using matlab. can anybody help me out for writing the codes please?

Here is the one sample file data:

    DISTRIBUTION: monomodal log-normal
    n    :  1.000
    r_mod:   .010
    sigma:  1.400
    number conc., surface. conc., volume conc. 
     .1087E+01     .1866E-02       .7878E-05
    part. ave. radius, surf. ave. radius, vol. ave. radius : 
     .1149E-01   .1169E-01   .1201E-01
    surface mean radius, volume mean radius : 
     .1267E-01   .1392E-01
    eff. variance : 
     .9939E-01

Let's say: I want to extract or read three parameters (r_mod, sigma, Surface means radius). The corresponding values for these three parameters from the file I put in this page is .010 , 1.400 , .1267E-01

The output should be (Which i want):

    r_mod   sigma   surface mean radius 
    .01     1.4        1.27E-02 
    .02     1.4        2.67E-02 
    .03     1.4        3.98E-02 
    ...     ..           .. ..  
    ..       ..         .. ..

I have more than thousands similar files in a same directory. I want to read all those files in matlab and the output should show in this way in a single file.
