How to have Matlab read files and then record the title of the file as a variable?

Hi everyone,

I have a set of files in a folder, like:

58.94177000.dpmrpt

62.586.dpmrpt

67.5467700.dpmrpt

77.331770000.dpmrpt

I need to read each file in Matlab, and record the title of the file like 77.331770000 as a variable, because it is a time variable.

Thank you.

S = {'58.94177000.dpmrpt', '62.586.dpmrpt'}

S = 1×2 cell array
    {'58.94177000.dpmrpt'}    {'62.586.dpmrpt'}

[~, timepart, ~] = fileparts(S)

timepart = 1×2 cell array
    {'58.94177000'}    {'62.586'}

Thank you Walter for your solution. How can I ask Matlab to read each file automatically instead of giving it the S set myself. For example, reading all the files in .dpmrp format in the folder D:\data\?

[Walter Roberson]

projectdir = 'D:\data';
ext = ".dpmrp";
dinfo = dir(projectdir, "*" + ext);
filenames = fullfile({dinfo.folder}, {dinfo.name});
nfiles = length(filenames);

[~, timepart, ~] = fileparts(filenames);

for K = 1 : nfiles
    thisfile = filenames{K};
    thisdata = Function_To_Read_dpmrp_File_Goes_Here(thisfile);
    results = Function_To_Process_Data_Goes_Here(thisdata);
end
