Hi, I have a text file with header, I need to import the file to matlab and to use numeric data. The numeric data in a line is separated by a ",". The file is as following Thanks Adelynne
base shear
Analysis Series = cyclic2 (cyclic2)
Load Case = [2] = [1] + cyclic

The functions that would be most helpful are 'fopen' and 'textscan'.
fid=fopen('yourtext.txt');
cdata=textscan(fid,'%f %f','delimiter',',');
fclose(fid);

just use textscan, and tell it you have how many header lines using HeaderLines options. Read Isakson's answer below...

cdata is a cell array. Read on cell array in the on-line help. And try
plot( cdata{1}, cdata{2} )

... but don't forget the header
fid=fopen('yourtext.txt');
cdata=textscan(fid,'%f%f','delimiter',',', 'HeaderLines', 3 );
fclose(fid);

fid = fopen('file.txt');
line1 = fgetl(fid);
res={line1};
while ischar(line1)
line1 = fgetl(fid);
res{end+1} =line1
end
fclose(fid);
res(end)=[]
data=res(4:end)
a=cellfun(@(x) regexp(x,',','split'),data,'un',0)
x1=str2num(char(cellfun(@(x) x{1},a,'un',0)'))
x2=str2num(char(cellfun(@(x) x{2},a,'un',0)'))

z=textread('filename.dat','%s','delimiter','\n')
z=z(4:end)
q=regexp(z,',','split')
data = reshape(str2double([q{:}]),2,16)'

The simplest way to read such data is in using the function txt2mat fro the File Exchange:
www.mathworks.com/matlabcentral/fileexchange/18430
Should the name of your data be Adely.txt , the following statement does the task:
A = txt2mat('Adelyn.txt','InfoLevel',0);
