Textread

[Erikve]

I'm sure that this will be a quite simple question, but I will not work for me. I try to read data from a csv-file (see under post). But is doesn't work... I try to skip the the first 9 ninen lines, because they are useless for the data analyses. I try the following line with matlab:
[data] = textread('data.csv','','delimiter',',','emptyvalue',NaN)

Can somebody help me to change this line? Thanks for every help!

greetings,
Erik

Hi,

try this :

[M{1:13}]=textread('data.csv', ...
'%d%d%d%d%s%d%d%d%d%d%d%d%d', ...
'headerlines',9, ...
'delimiter',';')

Thanks man, it doesn't give any errors! But there is second question, I want to use it... I get the following information of M:

M =

Columns 1 through 7

[63x1 double] [63x1 double] [63x1 double] [63x1 double] {63x1 cell} [63x1 double] [63x1 double]

Columns 8 through 13

[63x1 double] [63x1 double] [63x1 double] [63x1 double] [63x1 double] [63x1 double]

But simply use of M,1) doesn't show the first collumn, but:
[63x1 double]. So I want to see the contents

 

[dutmatlab]

TEXTREAD retunrs a cell array.

Read the documentation about this :

http://www.mathworks.com/access/helpdesk/help/techdoc/matlab_prog/f2-67323.html

To get the first elements of M :

M{1}
