 As for any matlab function, the documentation is built in. In the command window just type : **help** read_sunfluidh_data or **doc** read_sunfluidh_data.

 The *ins* files or more generally temporal series are ascii files in which the first column is time and the first line is a header. There is no special needs to have a script for these files. You can use directly builtin matlab functions that you can taylor to your needs.
-Conversely, you can use **read_sunfluid_probes.m** that attempts to read in the current directory all the *ins* files and build a structure with the variable names. It is quite fragile and may fail.
