To get the indices

ind = regexp(string, '(^|[^ ])[A-Z]');

To extract the strings from the indices

L{1} = string(1:ind(2));
for  i=2:numel(ind)-1
  L{end+1} = string(ind(i)+1:ind(i+1));
end
if numel(ind) > 1
  L{end+1} = string(ind(end)+1:end);
end

fid = fopen('filename','r') ;
S = textscan(fid,'%s','Delimiter','\n');
S = S{1} ;
%%Get the line number of your string 'STAX'
idxS = strfind(S,'STAX');   % find the index of your string 
idx = find(not(cellfun('isempty',idxS)));  % your required indices 
S(idx)
