cell consisting letters and numbers to matrix double

Hi,

I have a matrix containing 840x1 cells. These consist of 3 letters followed by numbers. Is there a way to convert this into 840x1 double?

I have tried str2double, but these returns only NaN. I tried several combinations with num2str, char, celstr, but i can't figure it out.

Thanks in advance!

Please give any meaningful example. What is the wanted result for 'ABC123'? How do you want to convert this to a number?

>> C  = {'ABC8', 'CAD90.87', 'ZED40'} ;
>> C2 = cellfun( @(s)s(4:end), C, 'UniformOutput', false ) ;
>> str2double( C2 )
ans =
    8.0000   90.8700   40.0000

EDIT 1: here is a solution that extracts both parts:

 >> data = textscan( [C{:}], '%3s%f' ) ;

With that you get

 >> data
 data =
  1×2 cell array
    {3×1 cell}    {3×1 double}

 >> data{1}
 ans =
  3×1 cell array
    {'ABC'}
    {'CAD'}
    {'ZED'}

 >> data{2}
 ans =
    8.0000
   90.8700
   40.0000

Hi,

Thank you for your quick response!

In your example, the ABC gets deleted. I do have to keep this, as this is the identification code. Is there a way to make that happen?

[Walter Roberson]

How do you want the 'ABC' to be encoded into the double that you need to be output?

Does it solve your problem of splitting alpha codes and numbers or do you still have a problem with that?
