To clarify: the 2 is a dimension argument for the any function. A==99 produces a matrix of logical values (T/F). By default any(A==99) applies an OR operation down each column, independently. So any(A==99,2) changes that to an OR operation across each row. The result is a column vector that is true wherever there's a 99 in the corresponding row of A.

ind=find(A==99.0000);
A(ind)=0;
A=A;
