Finding position of values which are equal to some value

Hello,

I am trying to find the position of values in the ND matrix (1X1800) which are equal to the val matrix (1X6) according to the code below. How can this be done for all values in val matrix in an easy way (i.e. val(2), val(3),...val(6))?

Your help is important.

[val,pos]=intersect(ND,NeD); % val: 1X6, pos:6X1, ND: 1X1800, NeD:1X200
[z1,zz1]=find(ND==val(1));

ND=randi(100,[1,1800]); % Random data just for testing
val=randi(100,[1,16]); % Random data just for testing
[common_val,idx]=intersect(ND,val,'stable')
