single quote

Hallo,
I want to make a string which has single quotes in it. My
idea is:

a='''%s';
for i=1:5
a=[a ' s%'];
end
a=[a ''''];

The result is:

a =

'%s s% s% s% s% s%'

This looks partly wright. But a should look like this:
'%s s% s% s% s% s%' which means without \.

Can anyone help me?

Hi Corinna,
first of all, this is a case where repmat can help, second, use 4 times ' to
get a string containing the single quote, so altogether:
a = ['''' repmat('%s ', 1, 5) '''']

Hallo,

sorry, but your solutions causes errors again:

xyz = ['''' repmat('%s', 1, 5) '''']

[patient1, patient2, patient3, patient4, patient5] = ...
textread
(source,xyz,factorsPerPatient, 'delimiter', '\t');

The error message is:

??? Trouble reading literal string from file (row 1, field
1) ==> 1 1 2 1 2\n

Error in ==> textread at 177
[varargout{1:nlhs}]=dataread('file',vara
rgin{:});

Error in ==> BeispielV3 at 26
[patient1, patient2, patient3, patient4, patient5] = ...

If I run the program with the original command ...textread
(source,'%s%s%s%s%s',factorsPerPatient, 'delimiter', '\t');
it works fine.

Any idea?

Hi Corinna,
just leave out the '''' at the beginning and the end:
repmat('%s', 1, 5) is already a string. When you call the original command,
you need to add the ' at the beginning and the end to construct a string.

xyz = repmat('%s', 1, 5) ;

[patient1, patient2, patient3, patient4, patient5] = ...
textread
(source,xyz,factorsPerPatient, 'delimiter', '\t');

should work fine.

Thanks, it is working. Now another question which I posted
a second a go with the title: textscan.

I want to read a tab-delimited txt-file. At the moment I
realisied it with textread. It works. Can any one show me
how it would work with textscan? I cannot realize it with
the Matlab-HELP. The original txt-file comes from exel and
consist of 3 rows and 5 columns.
The aim is to have the input in one variable from where I
than extract every information I need.

My solution with txtread:

[patient1, patient2, patient3, patient4, patient5] = ...
textread(source,'%s%s%s%s%s',3, 'delimiter', '\t');

In this case the bad thing is that I need to specifiy the
wright number of variables in the first breaket and
afterwards I have 5 for-loops to handle the informations on
into one variable - overviewTable=cell
(factorsPerPatient,numberOfPatients) - where the column i
stand for the patient i.

The inputfile looks like this:
1 1 2 1 2 <--row1
23 4 5 23 5 <--row2
6 7 8 9 10 <--row3

In each row the numbers are devided by tab! So the input
file consists of three rows.A new line seems to be realized
with /n.

Can you help me in this case,too?

Thanks,

another friend could help me. The solution is:

xyz = repmat('%s', 1, 5) ;
fid = fopen(source);
inputData = textscan(fid, xyz);
fclose(fid);
