How to load data with segments

Hi there,

I have a file, looks like below, it's Lon/Lat/Depth separated by ">". I tried to use importdata(), but only got first part. I need to plot some contour lines using geoplot(). Your suggestions will be appreciated.

> -660 contour -Z-660

288.9812 -7.0500 -660.0000

288.9884 -7.1000 -660.0000

288.9958 -7.1500 -660.0000

289.0000 -7.1777 -660.0000

> -660 contour -Z-660

289.0364 -7.4000 -660.0000

289.0454 -7.4500 -660.0000

289.0500 -7.4748 -660.0000

> -660 contour -Z-660

289.0741 -7.6000 -660.0000

289.0843 -7.6500 -660.0000

289.0948 -7.7000 -660.0000

289.1000 -7.7240 -660.0000

289.1056 -7.7500 -660.0000

289.1166 -7.8000 -660.0000

hello

I copied / pasted your data in a txt file

try this :

%% read one file 
clc
clearvars

filename = 'mydata.txt';
data = myreadfunction(filename)

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
function data = myreadfunction(filename)
    a = readlines(filename);
    [m,~] = size(a);
    data = [];
    % find / extract the different sets of data - separated by text "> -660 contour -Z-660"
    start_indexes = find(contains(a,'>'))+1;
    stop_indexes = [start_indexes(2:end)-2; m];
    
    for ci = 1:length(start_indexes)
        tmp = str2num(char(a(start_indexes(ci):stop_indexes(ci)))); % one segment of data
        data = [data; tmp];
    end
    
end

it gives :

data =

288.9812 -7.0500 -660.0000

288.9884 -7.1000 -660.0000

288.9958 -7.1500 -660.0000

289.0000 -7.1777 -660.0000

289.0364 -7.4000 -660.0000

289.0454 -7.4500 -660.0000

289.0500 -7.4748 -660.0000

289.0741 -7.6000 -660.0000

289.0843 -7.6500 -660.0000

289.0948 -7.7000 -660.0000

289.1000 -7.7240 -660.0000

289.1056 -7.7500 -660.0000

289.1166 -7.8000 -660.0000
