You can use 'textscan' or 'textread' functions

Answer 1

NumHeaders = 17;     %for example
NumDataLines = 1234; %for example
ColNum = 8;          %for example
fmt = [ repmat('%*s',1,ColNum-1), '%f%[^\n'] ];
fid = fopen('C:\...\yourfilename.txt', 'rt');
data = textscan(fid, fmt, NumDataLines, 'HeaderLines', NumHeader);
fclose(fid);

fid = fopen('C:\...\yourfilename.txt', 'r');
if fid == -1, error('Cannot open file'); end
data = fscanf(fid, '%g', [1, Inf]);
fclose(fid);
