tmp(tmp < 32) = []

This remove all control characters, e.g. char(10), the line break.

MATLAB: Remove the first five letters of a string

str = str(6:end);

MATLAB: Delete the string symbols on specific line with special symbol.

Here we use fileread() to read your txt file into matlab and then we put each line of text into a cell array. Using regexp() we find which lines start with the pattern "# ****" where the asterisks are numbers. Then we replace those lines with your new pattern: "# *" and write it to a new text file using fprintf().

txtFile = 'C:\Users\name\Documents\MATLAB\mlc.txt'; 
% Read file and store each line in a cell
txt = fileread(txtFile);
txtCell = strsplit(txt, newline)'; 
% Find rows that start with '# ####'
hasPattern = regexp(txtCell, '# \d+');          %this searches for "#' followed by 1 space and at least 1 number.
rowIdx = find(~cellfun(@isempty, hasPattern));  %row numbers that will be replaced
% Replace the rows with new text
newText = strsplit(sprintf('#    %d|', 1:length(rowIdx)), '|');   %Here's where you create the new text; ignore last element. 
txtCell(rowIdx)  = newText(1:end-1); 
txtCell = cellfun(@(x)sprintf('%s\n',x), txtCell, 'UniformOutput', false); %add 'newrow' char
% Write text to new file (or you could overwrite the old one).
newFile = 'C:\Users\name\Documents\MATLAB\mlcNEW.txt'; 
fid = fopen(newFile, 'wt'); 
fprintf(fid, [txtCell{:}]);
fclose(fid);

Your new txt file will look like this

#    1
PLV   12.20 1.00 Pg
PLV   21.00 0.75 Sg
HNV   16.20 1.00 Pg
HNV   28.40 0.75 Sg
#    2
PLV   12.20 1.00 Pg
PLV   20.60 0.75 Sg
