Read data from text file. Tables with uneven number of rows

조회 수: 2(최근 30일)
I have data of following shape.
I need to save all the numerical values in tables from the file as matrices. The problem is that all the tables have different number of rows. What would be the best way to go about solving the problem. Thanks

How do you want the data combined together? If you combine everything into a single table then you will have rows from different trajectories. Is that OK? Can you provide more information about what you want?

fid = fopen('t1.txt');
c = 1;
while ~feof(fid)
d = fgetl(fid);
if ~isempty(regexp(d,'X.*Y.*Z.*Energy', 'once'))
part = textscan(fid,'%f%f%f%f');
data{c} = [part{:}];
c = c+1;
This uses fgetl to find the headers, then textscan reads the arrays.
