For the subscripted indexing, internally, Matlab will not create the linear index, but it will use a (double) compiled loop to cycle through all elements. The subscripted version on the other hand will have to loop … NettetConvert a linear index of a 3-D array to a subscript index. Create an array, and find the subscript index corresponding to the 14 th element of the array. A = rand (3,4,2); [row,col,page] = ind2sub (size (A),14) row = 2. col = 1. page = 2. Check that both index versions refer to the same element of the array.

NettetA linear index allows use of a single subscript to index into an array, such as A(k). MATLAB ® treats the array as a single column vector with each column appended to the bottom of the previous column. Thus, linear indexing numbers the elements in the columns from top to bottom, left to right. For example, consider a 3-by-3 matrix.
