MATLAB: Read .txt file data with data between specific lines “string” .

txt

I want to read data between ( strings ) line starting from " *Node " and

ending at and next (strings ) line " *Element, type=C3D4" .

The textscan function using a numeric format descriptor string will automatically stop when it encounters:

*Element, type=C3D4

so this is actually a straightforward problem:

fidi = fopen('Copy_of_Job-1.txt','rt');
D = textscan(fidi, '%f%f%f%f', 'HeaderLines',9, 'Delimiter',',', 'CollectOutput',1);
fclose(fidi);

with ‘D’ being a (1418x4) double matrix.

FileID = fopen('data.txt','r');
C = textscan(FileID,'%s %f %f','HeaderLines',1,'Delimiter',',');
fclose(FileID);
C{1}
C{2}
C{3}

I would use the textscan function instead. Something like this would work:

fidi = fopen(filename,'rt');
D = textscan(fidi, '%f%f%f%f', 'Delimiter','\t', 'HeaderLines',2, 'CollectOutput',1);

Experiment with it to get the result you want.
