Hi Daniel,
Even though you can find such patterns easily in 1-D arrays by converting them to strings (link1 and link2), it would be better if you can write such pattern funcitons for 2-D arrays.
for i=1:r
for j=1:c
answer = check_for_triangle(i,j);
end
end
function check_for_triangle(r, c)
is_present = false;
if A(r,c) == 1
if A(r+1,c) == 1 & A(r+1,c+1) == 1
if A(r+2,c) == 1 & A(r+2,c+1) == 1 & A(r+2,c+2) == 1
is_present = true;
end
end
end
end
The above given pseudo-code is an example of how you can write code pattern to check for a triangle in a binary adjacency matrix.
