I want to extract x,y co-ordinate and amplitude data from the txt file but i am not getting any idea how to do so.
for eg.:- * Gp# 1[8,4] x,y = -14.46, 0 dT[7] Src Amplitude = 36.0
then i want output as
x y amplitude
1. -14.46 0 36.0
2.
3. and so on

fid=fopen('abc.txt','r');
abc=textscan(fid,'%s',inf,'Delimiter','\n','HeaderLines',2,'commentstyle','1','texttype','string');
fid=fclose(fid);
abc=string(abc{:});
abc=abc(contains(abc,'Gp#'));
xy=str2double(split(extractBetween(abc,'x,y = ',' dT'),','));
ampl=str2double(extractAfter(abc,'Amplitude = '));
tABC=table(xy(:,1),xy(:,2),ampl,'VariableNames',{'x','y','amplitude'});
results in
>> head(tABC)
ans =
8×3 table
x y amplitude
