Hi, I have a document with a whole bunch of header information and description. After about 20 lines it goes into the useful data. Each line of data is formatted like this: P 1 1234.939 1234.505 1234.505 102 where P just denotes that it is data, 1 is a satellite number and the data is X Y Z and time. Does anybody know how to import this data into useful variables X Y Z and time? I am thinking it will be textscan or something, but I have never used data in this format before. Thanks for any help.
