xx = '[10,10]'

I want to convert the string xx to a number and extract the first and second value in a single line. What I am trying to do is extract the 1st and 2nd value without storing them in any variable.

Is there any solution to this? Thanks!

Rather complicated:

subsref(str2double(regexp(xx,'\d*','match')), substruct('()', {2}))
