MATLAB: Textscan Issue (Reading file that starts with text and finishes with numerical data)

textscan

Hi, I am using textscan to read over a dataset of .asc files.
# Phase     = a
# Cycle     = 002
# Pass      = 0015
# Equ_time  =  244739511.104659 (03-Oct-1992 15:11:51)
# Equ_lon   =  261.498950
# Original  =  GDR-M of 1996-151T07:29:48
# Col  1    = time rel. to equator passage [s]
# Col  2    = latitude [degrees_north]
# Col  3    = longitude [degrees_east]
# Col  4    = sea level anomaly [m]

I want textscan to not read the lines of text and to instead write the columns of data to a matrix C as I attempted here.
fid = fopen('txp0015c002.asc');
C = textscan(fid,'%f %f %f %f', 'delimiter', '#');
fclose(fid);
disp(C);
Instead, I get a 1×4 matrix of empty values. Please help!!

Best Answer

I would use:
C = textscan(fid,'%f %f %f %f', 'HeaderLines',10, 'delimiter', '\n', 'CollectOutput');
