create output structure within a function

Hi,
I have problems getting the data output in a structure. I made a function in which I do several things. In the end, I want to have an output structure which contains different parts of the data.
this is how the script starts: function [output] = interpolate_csv (filename)
In the end I create the output like this: output = struct('pathstr','name','ext','baseline', 'postbaseline','postbaseline_baseline_corrected_0_500ms', 'postbaseline_baseline_corrected_500_1000ms', 'postbaseline_baseline_corrected_1000_1500ms', 'postbaseline_baseline_corrected_1500_2000ms', 'postbaseline_baseline_corrected_2000_2500ms', 'postbaseline_baseline_corrected_2500_3000ms', 'postbaseline_baseline_corrected_3000_3500ms', 'postbaseline_baseline_corrected_3500_4000ms')
All I get is this:
output =
''
What do I need to add to the script?
Thank you for your help.
best, Mariska

unless you mean this:
output = struct('pathstr','name','ext','baseline', 'postbaseline',{'postbaseline_baseline_corrected_0_500ms', 'postbaseline_baseline_corrected_500_1000ms', 'postbaseline_baseline_corrected_1000_1500ms', 'postbaseline_baseline_corrected_1500_2000ms', 'postbaseline_baseline_corrected_2000_2500ms', 'postbaseline_baseline_corrected_2500_3000ms', 'postbaseline_baseline_corrected_3000_3500ms', 'postbaseline_baseline_corrected_3500_4000ms'})
output =
1x8 struct array with fields:
pathstr
ext
postbaseline
>> output(1)
ans =
pathstr: 'name'
ext: 'baseline'
postbaseline: 'postbaseline_baseline_corrected_0_500ms'

output=struct('postbaseline',[postbaseline_baseline_corrected_0_500ms,postbaseline_baseline_corrected_500_1000ms]);
or
output=struct('postbaseline',[postbaseline_baseline_corrected_0_500ms;postbaseline_baseline_corrected_500_1000ms])

Do you mean
output=struct('pathstr',name,'ext',baseline,...)?
check the syntax of struct() again.

If I run your line directly, I got
??? Error using ==> struct
Field and value input arguments must come in pairs.
Check to make sure you always have the struct('param',value) with 'param' and value paired.

@Mariska: You did not get Jiangs point. It looks like you define the STRUCT with only the field names, but forget to insert the data also. But the syntax of STRUCT is: struct(name1, data1, name2, data2, ...).
