Hexadecimal data processing in Matlab - matlab

Question

I have a string of Hex data streaming out as my data, it looks like this:
"00 E1 08 A2 05 FF"
I need them concatenated and then converted to decimal in column format, something like this:
00E1
08A2
05FF
Finally after conversion to decimal:
225
2210
1535
Total data available is 70,000.
Anyone can help me? I'm a newbie in Matlab, I tried writing the following code but no luck.
N=140000; %N is the number of data
n=N/2; %n is the number of concatenated data
filename=input('\nFile-name: ','s');
data_import=importdata(filename,' ', 1);
data_char=char(data_import);
data_str=sscanf(data_char, '%s', [N,1]);
data_out=textscan(data_str, '%4c',n);

Answer 1

importdata based approach -
data_import = importdata(filename,'')
C = regexp(data_import,' ','Split')
C1 = C{:}
t1 = reshape(C1(~cellfun(#isempty,C1)),2,[]).' %//'
data_out = hex2dec([char(t1(:,1)) char(t1(:,2))])
Alternative textscan based approach -
fileID = fopen(filename);
data_import = textscan(fileID,'%s')
fclose(fileID);
t1 = reshape(data_import{:}.',2,[]).'
data_out = hex2dec([char(t1(:,1)) char(t1(:,2))])

Answer 2

filename=input('\nFile-name: ','s');
data_import=importdata(filename,' ', 1);
data_char=char(data_import);
data_str=sscanf(data_char, '%s', [N,1]);
data_out = [];
for i=1:4:N
a = data_str(i:i+4);
d = hex2dec(a);
data_out = [data_out;d];
end
Hope this helps..
Edit:
Example String: 00 D5 00 CE 00 C7 00 C0 00 B9 00 D5 00 CE 00 C7 00 C0 00 B9 00 D5 00 CE 00 C7 00 C0 00 B9
Code:
data = '00 D5 00 CE 00 C7 00 C0 00 B9 00 D5 00 CE 00 C7 00 C0 00 B9 00 D5 00 CE 00 C7 00 C0 00 B9';
a = regexprep(num2str(data,17), '\s', '');
sizeOfA = size(a,2);
data_out = [];
for i = 1:4:sizeOfA
a1 = a(i:i+3);
d = hex2dec(a1);
data_out = [data_out;d];
end
