Thanks Serge,
That seems to be the most convenient solution to me.

You can proceed as follow without any change in your file:
u=mopen("myfile","r");
header=mgetl(u,4)
data=mfscanf(-1,u,"%f %f\n")

Hi,
with
x=read(file,-1,2)
I can read the data from a text file containing e. g.
1 2.12 First line of text file
2.12 3.2
3 2
4 2
5 2.
6 2
7 2
Last line empty
What can I do to read only the numbers from a text file like
Header 1 First line of text file
Header 2
1 2.12
2.12 3.2
3 2
4 2
5 2.
6 2
7 2
Last line empty
where the data start in the 5th line?

Re: [Scilab-users] Reading numericaldata from txt file containing headlines
Thanks Amanda, that helps.
In the meantime I have found an alternate way by editing the text file:
Move the leading text lines to the end of the data colums.
Append a hint after the first data line that there is information below.
Use
x=read(file,r,c)
where r and c define the row and colum number of the numerical data.
That works even for my chaotic data format wherein different numbers of
blanks and tabs in each line separate the data.
Regards, Jens

Hi,
if your data it's tabular, in another words, you can open it in Excel
or Libre Office Calc like you whant to do.
You should be able to read in the same way with csvRead, however you
need to adjust the parameters
Something like:
[M,comments] =csvRead('myfile.txt','',[],[],[],[],[],5);
Note that ' ' need to be the same separator in your text file.
*May be* it can be a TAB (the key in keyboard) or a simple space, you need try
or open your file and check it.
And the 5 value it's to ignore the first 5 lines.

Is that what you are looking for ?
