Just use [] for any column or row that you want to remove.
Eq :
A = round(10*rand(10));
B = A;
B(3, :) = []

MATLAB has a maximum size of matrices. It is limited by the amount of elements in a matrix not by the dimension. The computer command gives you that limit:
[str,maxsize] = computer returns the integer maxsize, the maximum number of elements allowed in an array with this version of MATLAB
And of course the it depends on the memory and bitness of your system:
