Importing Matrix of mixed types into Matlab

[jwbrooks]

Hi, I'm new to the community.

I'm trying to import data from a tabulated data file, but the data contains both strings (rows 1 to 23) and a large number of floats (rows 24 and on). What I want to do is be able to load all of the floats (rows 24 and on) into Matlab while ignoring the rest, but I have no idea how to go about doing that. I've played with textscan and textread, but I haven't been able to figure it out. I would really appreciate anyone who could shine some light onto this for me.

I've attached a sample data file.

Try this

[t,x,y,z] = textread('temp.txt','%f %f %f %f' ,'headerlines',23);

I currently use a modified version of "hdrload"

It scans the both the header and data, any size in either, and outputs both in case you need it. Very robust little script.
