Grammar:
IND = Find (x)
ind = Find (x, k) ind = Find (x, K, ' a '
)
ind = Find (x, K, "last")
[Row,col] = find (x, ...)
[Row,col,v] = Find (X, ...)
IND = FIND (x) queries the position of a non-0 element, and if X is a row vector, returns a row vector, otherwise, returns a column vector. If x is all 0 elements or an empty array, an empty array is returned.
