vector x and matrix A
x = [1 2 3 7 8 9 13 22 30 ]
A =[1 3 6 9
2 12 13 8
3 3 6 7
4 22 31 30

and i want to have value in matrix A accordding a vector x
and replace it by a new value like to add 10000
without changing a first column in A

x = [1,2,3,7,8,9,13,22,30];
A = [1,3,6,9;2,12,13,8;3,3,6,7;4,22,31,30;5,8,9,33];
ida = ismember(A,x);
ida(:,1) = false;
A(ida) = A(ida)+1000
A = 5×4
1 1003 6 1009 2 12 1013 1008 3 1003 6 1007 4 1022 31 1030 5 1008 1009 33
