I am trying to find values in a matrix for specific indices. I have a 180×180 matrix, N, and have a range of dx and dy values. How do I scan matrix N to find values for which the combination of [i,j] coordinate in the matrix is the [dx,dy] pair values? For example, if dx(3) = 5 and dy(3) = 10, I want to return the matrix value at i = 5, j = 10. Or if I have dx(2) = 1, dy(2) = 5, I want to return the matrix value at i = 1 and j = 5. I want to do this over the entire range of dx and dy.
dx = [0 1 3 10 15 12 4 7];dy = [1 4 62 1 33 4 10 22];N11 = randi([0,5],45,45);N12 = randi([1,4],45,45);N13 = randi([0,7],45,45);N14 = randi([0,6],45,45);N21 = randi([1,3],45,45);N22 = randi([1,7],45,45);N23 = randi([4,6],45,45);N24 = randi([2,7],45,45);N31 = randi([1,4],45,45);N32 = randi([6,7],45,45);N33 = randi([1,7],45,45);N34 = randi([3,4],45,45);N41 = randi([2,5],45,45);N42 = randi([0,3],45,45);N43 = randi([5,6],45,45);N44 = randi([0,4],45,45); N = [N11 N12 N13 N14; N21 N22 N23 N24; N31 N32 N33 N34; N41 N42 N43 N44];
