As an export from a sensor I have my data in a .csv data. However, the .csv data separates in two different columns the values of the integer and the decimal point. When importing the data I would like to merge these two columns and seperate them with a decimal point. I do not know how this works. I have already tried combining the two vector columns using sscanf(sprintf(...)) and dividing it by 100, however the amount of digits in my decimal part (Column B) is not consistently the same.
A B
0 15
1 2
3 12
0 02
What I would like to have as a result is:
C
0.15
1.2
3.12
0.02
Can anyone give me some advice?
Thanks! :)

Can you attach an example of the csv file. Possibly, the problem can be fixed by a better import rather than trying to fix it after the fact.

This is the data. In this case i always need to combine each column "xxx1" with "xxx2" to create a third column.
I have been using the solution proposed by KSSV for the moment, which does give me the answer I want with a simple mathematic formula.

Let A be integer and B be decimal
iwant = A+B/10 ;

f = fopen('your file name.csv', 'r') %
data = textscan(f, '%s');
fclose(f);
your_data = cellfun(@str2num, strrep(data{1}, ',', '.'))
