Description |
sub = ind2sub1(siz, ind)
Multiple subscripts (written into one vector or matrix) from linear index "ind" for an N-dimensional array defined by its array size "siz".
Linear index "ind" can be a single positive integer or a vector of positive integers. If "ind" is a row vector, it is converted into a column vector internally.
In principle, the same as MatLab routine "ind2sub", but the result is put into an automatically sized vector (if "ind" is a single integer) or matrix (if "ind" is a vector) rather than into multiple variables.
Example:
A = ones(2, 3, 4);
Sub1 = ind2sub1(size(A), 6)
Sub1 =
2 3 1
Sub2 = ind2sub1(size(A), 4:4:24)
Sub2 =
2 2 1
2 1 2
2 3 2
2 2 3
2 1 4
2 3 4
