MATLAB: How to exclude specific values from a vector

excluding values from a vector;

I have two arrays of unmatching sizes.

For example: A=[1;2;3;4;5;7;14;76;89] B=[2;3;14]

What I would like as an output is a new vector which has all the values from A excluding values from B. So C=[1;4;5;7;76;89] I am unable to overcome unmatching dimension issues with my basic matlab skills 🙁

Any help would be really appreciated!

 C = setdiff(A,B);

Hi Abhijit,

try

x  = 1:n;
