Web% the closer of the two original points in an adjacent *column* to the % closest point, INDEX{3} is likewise in an adjacent *row* to the closest % point, and INDEX{4} is in both an adjacent row and an adjacent column. % % BOOL is a boolean array that is true whenever all four of the indices % in INDEX are well-defined. WebMost often, indexing in matrices is done using two subscripts - one for the rows and one for the columns. The simplest form just picks out a single element. A(2,4) % Extract the element in row 2, column 4 ans = 8 More generally, one or both of the row and column subscripts can be vectors. A(2:4,1:2) ans = 5 11 9 7 4 14
