how to normalize data?

Hi all
I have a wrong program step. I don't know what is wrong with my program script.
I have data per 10 minutes which is divided into 7 columns, time and data.
09/10/2014 3:00 0
09/10/2014 3:10 0
09/10/2014 3:30 0.4
09/10/2014 3:50 0.4
09/10/2014 4:00 0.4
09/10/2014 4:10 0.4
09/10/2014 4:20 0.4
09/10/2014 4:30 0.4
10/10/2014 4:40 0.4
09/10/2014 4:50 0.4
09/10/2014 5:00 0.4
09/10/2014 5:10 0.4
09/10/2014 5:20 0.4
It can be seen that at 3:20 a.m. and the value of the data is empty, I want to get data per 10 minutes with empty data filled with 0 / nan.
I use matlab 2014b. there is no retime function so I have trouble ... I have asked before in this forum but have not received suggestions that are in accordance with this program. I attach the following data. I say thank you to anyone who has tried to help and advise ...

How are you collecting data? Is it through internal code or through ThingSpeak? Can I see the code you are using.

The attached data do not match the example you provided in your question. Are we tp assume the columns in your data are [year, month, day, hour, minute, fraction-of-minute]?
>> sample(1:5,:)
ans =
2014 8 10 8 20 0 0
2014 8 10 8 30 0 0
2014 8 10 8 40 0 0
2014 8 10 8 50 0 0
2014 8 10 9 0 0 0
What's column 1? At the end of the matrix there are weird year numbes.
>> sample(end-6:end,:)
ans =
37 6 5 22 50 0 0.4
37 6 5 23 0 0 0.4
37 6 5 23 10 0 0.4
37 6 5 23 20 0 0.4
37 6 5 23 30 0 0.4
37 6 5 23 40 0 0.4
37 6 5 23 50 0 0.4
Row #95 doesn't have a day value
>> sample(95,:)
ans = %v
2014 9 10 0 0 0 0
The data needs a bit more explanation and/or cleaning.

Sometimes merely discussing the problems leads the questioner to their solution ;)
