I have a huge file with first real numbers and then complex numbers(file attached). I want to read the file and store the real numbers as variable frequency , first 5 rows of complex numbers as unit_1 and remaining as unit_2. Kindly help. Thanks.

If "huge" is a fraction of the size of the memory:
str = fileread( 'try_file.txt' );
ixc = find( str=='(', 1, 'first' );
cac = textscan( str(1:ixc-1), '%f%f%f%f%f%f', 'CollectOutput',true );
num = cac{1};
cac = textscan( str(ixc:end), '%f%f%f%f', 'CollectOutput',true ...
, 'Delimiter',{'(',')',','}, 'MultipleDelimsAsOne',true );
z = complex( cac{1}(:,[1,3]), cac{1}(:,[2,4]) );
and inspect the results
>> whos num z
Name Size Bytes Class Attributes
num 13x6 624 double
z 11x2 352 double complex
>> num(1,:)
ans =
97.0210 97.0600 97.0990 97.1380 97.1770 97.2160
>> z(1,:)
ans =
0.1818 + 0.0572i 0.0274 + 0.4233i
