Hello ,I Have a text file which i mannaged to sliceout one subtable from it.(attched txt file)

and convert the frequency string to a number array.

next i ned to convert the string array of data into number array but its more difficult.

each cell is of form '(-7.30313259052058e-002dB,-4.26354774426478e+000°)'

in the end of this script i am trying to use text scan however it gives me two empty cell with square symbols in them.

i would like to get the D array into other array 2X1000 with the numbers in them.

Thanks

fid=fopen('testnew1.txt');
g= textscan(fid,'%s','delimiter','\n');
leng=length(g{1});
fclose(fid);
k=1;
for j=3:1:1002
  f_str(k)=g{1}(j,1);
  
  C= strsplit(char(g{1}(j,1)),'\t');
 F(k) = strsplit(char(C{1}),' ');
 D(k)=strsplit(char(C{2}),' ');
 frec_subtable(k) = str2num(F{k});
 %m(k) = textscan(D(k),'%d');
%cords4= textscan(t, '(%fdB%f)');
h = textscan(D(k), '(%4fdB%f°)', 'Delimiter',',')
 k=k+1;
end
