Convert text of multiple digits to numbers

if i have a variable x containing in each row something like this :

• 123123123
• 123798731
• 234874343

if i use class(x) it prints char . and if i write cellstr(x) i get :

• ' 123123123 '
• ' 123798731 '
• ' 234874343 '

how can i convert x to column of numbers so :

1- each row is a number meaning x(1) = 123123123 and not 1.

2- i would be able to use meshgrid(x,x) and i would get the output :

123123123 123798731 234874343

123123123 123798731 234874343

123123123 123798731 234874343

thanks

A={' 123123123 '
' 123798731 '
' 234874343 '}
str2double(A)

if i did y=str2double(x); then y(1) is 1.0231e+020

No

x={' 123123123 '}
str2double(x)

ans =

   123123123

same output for both ways , see pictures below.

well... the problem was that my numbers were long like 24-25 digits and matlab couldnt print it that long (although i used format long), but in general your method works , thank you.
