MATLAB: Insert elements into vector

index = [1;2;4;5;6;8;9];
index_val = [11;25;3;4;56;7;9];
removed_index = [7,3];   % simpler to use a numeric array

removed_val = [1.1,3.2]; % simpler to use a numeric array

Then all you need is:

idx = [index(:);removed_index(:)];
vec = [index_val(:);removed_val(:)];
vec(idx) = vec
idx(idx) = idx
