The find function finds the indices of all matrix elements which do not equal 0.
Return Value
rvIndexes contains the indices of the elements of rvM which are not equal to 0.
Parameters
rvM is a real matrix. If all matrix elements are equal to 0 (zero) the function will return 0.
Comment
find is mainly used in conjunction with comparison operators. If rvM is a matrix, the function returns the indices of the internal representation of the matrix.
Example
a = [1, 2, 6, 45, 3, 11]
b = find(a >= 6)
print a[b] // Output: 6 45 11
a = ["abc", "def", "jkl"]
b = find(a != "def")
print b // Output: 1 3
print a[b] // Output: abc jkl
