matlab怎么找出奇数个数,matlab-从（奇数）字符串中提取数字

I have a series of strings in a cvs file, they all look like the two bellow:

7336598,"[4125420656L, 2428145712L, 1820029797L, 1501679119L, 1980837904L, 380501274L]"

7514340,"[507707719L, 901144614L, 854823005L]"

....

how can I extract the numbers in it?

Sorry for the beginners question...and thank you for having a look! :)

Edit: the size of each line is variable.
