Hello, I need to use data in text file as a input to my matlab code. The data format in text file is as follows(each row has 4 columns: 1 for time, 2 for st. number, 3&4 are velocity components), Sample data:
Time St. DA DB
0 33 38.55 -10.87
2 33 37.35 -84.84
4 10 37.22 -62.29
6 43 37.39 -41.00
8 43 37.00 -19.75
I need to compare the time and st. number value with the values in my matlab code and pick 3&4 accordingly for further analysis. Any inputs are welcome.

Try using textscan. You should read the documentation and pay attention to the option HeaderLines, and how FormatSpec is defined.
It is also important to use fopen and fclose, something like this:
fid = fopen('mydata.txt','rt');
C = textscan(fid,'%s %s %f32 %d8 %u %f %f %s %f');
fclose(fid);

If you want a table instead of a cell array, you can simply do
t = readtable(filename);
No need for fopen(), a format string, and fclose. I think it's a lot simpler but it requires release R2013b or later.
