How to convert a char array into a double array?

I have a character array (68*1 int8)

Y = Columns 1 through 9

   49   52   55   52   51   52   46   55   50

Columns 10 through 18

   54   56   54   44   32   51   44   32   32

Columns 19 through 27

   32   48   46   48   48   48   44   32   32

Columns 28 through 36

   48   46   48   55   56   44   32   49   48

Columns 37 through 45

   46   52   51   52   44   32   53   44   32

Columns 46 through 54

   32   55   51   46   57   51   56   44   32

Columns 55 through 63

   54   55   46   53   54   50   44   45   56

Columns 64 through 68

   52   46   56   49   50

The real data looks like this

X  = 147434.72686, 3,   0.000,  0.078, 10.434, 5,  73.938, 67.562,-84.812

It is a CSV array. I want to convert this into a double array, So that I can access each of the values in X as a decimal number.

edit: I'm sorry if the question wasn't clear. I'm getting IMU data from my phone on to matlab, the UDP packets which are actually like X is sent as Y. So inorder to do my computation I need to convert this back to floating point values.(ie change Y to X)

Y is not a character array

Please show us how you import the CSV file. If the file is imported by a sufficient method, no conversion is required afterwards.

Y looks like ASCII values of characters. Are X and Y both in the same CSV file, or are they in different CSV files? And what do you mean by "real"? If X is in a csv array and you read it in with csvread() then x is already a double (decimal number). What relationship, if any, does X have to Y? Y seems to be repeated values like ASCII values of characters '0' through '9', while X seems to be floating point numbers all over the place with no relationship at all to Y.

Please check the edited question. I hope it clears things.

Oh, I see now. You're getting x as an ascii string. So the values of Y are the ASCII values of each character of the X.

Y =[49   52   55   52   51   52   46   55   50,...
 54   56   54   44   32   51   44   32   32,...
 32   48   46   48   48   48   44   32   32,...
 48   46   48   55   56   44   32   49   48,...
 46   52   51   52   44   32   53   44   32,...
 32   55   51   46   57   51   56   44   32,...
 54   55   46   53   54   50   44   45   56,...
 52   46   56   49   50];
Y(Y==44) = ' ' % Make separator be a space.
x = cell2mat(textscan(char(Y),'%f'))

[HJ Jay]

Thanks a lot, Image analyst.

Answer 2

>> v=str2num(char(cell2mat(Y)))
v =
 1.0e+05 *
  1.4743    0.0000         0
>> v(2)
ans =
   3
>>

But, why don't you read the csv file as numeric to begin with????

Sorry, but I'm afraid it's not working. I've edited the question to get rid of some ambiguity.
