Complete matrix with vectors as indices in matlab

Question

Let us say that we have a matrix A1 and two vectors v1 and v2 as follow:

A1=zeros(5, 5);
v1=[1 2 3];
v2=[5 5 4];

Is there a way to replace the

Answer 1

Convert your vectors into linear indices:

A1=zeros(5, 5);
v1=[1 2 3];
v2=[5 5 4];

ind=sub2ind(size(A1), v1, v2);
A1(ind(1))=1

A1 =

     0     0     0     0     1
     0     0     0     0     0
     0     0     0     0     0
     0     0     0     0     0
     0     0     0     0     0

etc.
