I have a 4x4 matrix with indicies indicated around it (k). I want to map it to an 8x8 matrix based on thoes indicies to give me k'. See the image below for clarification. Is there a way to do it such that the indecies on the 4x4 matric and be any value from 1-8. For instance instead of 7812, use 4312 or 4378.

How are the indices given to you? Or how are these indices provided to the code as input?

A smarter example than only 1
K = [1,2,3,4; 5,6,7,8; 9,10,11,12; 13,14,15,16];
index1 = [7,8,1,2];
index2 = [7,8,1,2];
