Str to double in matlab

Question

I have a variable lets say x, that contain chars as follow :

123123213
343423434
454545455
....

If i do :

x(1) = 1 
x(1,1:9) = 123123213

I want to be able to get when i write :

x(1)=123123213 

I tried doing:

s=[cellstr(x)];
t=[str2double(s)];

Then i got "t" something like that :

ans =

1.0e+020 *

   1.1352
   1.1006
   1.0835
   ....

Answer 1

Maybe str2num:

x = ['123123123';'343423434';'454545455']

x_num = str2num(x);

x_num(1)

ans =

   123123123
