How to find the closest value between a matrix and a vector and print out its index?

For example the vector is [3 4 5 6] and the matrix is a 4x4, i want to compare each element of the matrix with the vector and place all indices of the four near elements in a vector.

Can you give an example using an example 4x4 matrix? What is the expected output for that example?

What is four near elements? Makes no sense to me.

[Mohannad Alzard]

The elements of the vector are compared with all the elements of the matrix, and the nearest value from the matrix with respect to the vector its index is placed in a another vector, this should be repeated until all the elements of the vectors are compared with the elements of the matrix.

You mean something like this?

I=[];
for k=1:length(v)
    [~,idx]=min(abs(m-v(k)),[],'all','linear');
    I=[I,idx];
end

Yes Thank you so much!.
