WebFind the nonzero elements in a 4-by-2-by-3 array. Specify two outputs, row and col, to return the row and column subscripts of the nonzero elements. When the input is a multidimensional array ( N > 2 ), find returns col as a linear index over the N-1 trailing dimensions of X. X = zeros (4,2,3); X ( [1 12 19 21]) = 1 Web27 feb. 2015 · Even when all elements of values are non-zero vectors of doubles (which is a non-error case). But it also needs to be robust for the case, when one cell element is a double 0, which is valid. – Robert Seifert Oct 14, 2013 at 10:19 Add a comment Your Answer Post Your Answer
