Subscripted reference for qrandset
x = p(i,j)
x = subsref(p,s)
x = p(i,j) returns a matrix that contains a subset of the points from the point set p. The indices in i select points from the set and the indices in j select columns from those points. i and j are vector of positive integers or logical vectors. A colon used as a subscript, as in p(i,:), indicates the entire row (or column).
x = subsref(p,s) is called for the syntax p(i), p{i}, or p.i. s is a structure array with the fields:
| type | string containing '()', '{}', or '.' specifying the subscript type. |
| subs | Cell array or string containing the actual subscripts. |
| Command | Returns |
|---|---|
| p = sobolset(5); | The fifth point |
| x = p(1:10,:) | All columns of the first 10 points |
| x = p(end,1) | The first column of the last point |
| x = p([1,4,5], :) | Points 1, 4, and 5 |
