I have a huge file with data format:
(2,4) (5,6)
(34,26) (22,78)
(18,76) (33,50) etc.
I want to create 4 matrix with data as(2,34,18) ; (4,26,76); (5,22,33) and (6,78,50). I used textscan to read the data but couldn't use it aptly. If anybody could guide me with it, it will be very helpful.

Make it easy for people to help you by attaching the file. We don't need all 42 terabytes of it, just a few lines.

Two variants
fid = fopen( 'cssm.txt' );
cac = textscan( fid, '(%d,%d) (%d,%d)', 'Whitespace','' ...
, 'Delimiter',' ', 'CollectOutput',true );
fclose( fid );
num1 = cac{1};
fid = fopen( 'cssm.txt' );
cac = textscan( fid, '%d%d%d%d', 'MultipleDelimsAsOne',true ...
, 'Delimiter','(),', 'CollectOutput',true );
fclose( fid );
num2 = cac{1};
m1 = permute( num2(:,1), [2,1] );
m2 = permute( num2(:,2), [2,1] );
m3 = permute( num2(:,3), [2,1] );
m4 = permute( num2(:,4), [2,1] );
Inspect the result
>> all(all(num1==num2))
ans =
1
>> num2
num2 =
2 4 5 6
34 26 22 78
18 76 33 50
>>
Do you really want m1,m2,m3 and m4?
