IEQUAL

Syntax: | `scalar = IEQUAL(vector,scalar)`

The `IEQUAL` function returns the index of `vector` which corresponds to where `vector` is equal to the value of `scalar`, that is, `IEQUAL` returns the first `j` where `vector[j] = scalar`. If the value of `scalar` is not in `vector` then `IEQUAL` returns zero (0).

Example

Suppose you have vector `X = [1;2;3;4;5]`. If you enter `A=IEQUAL(X,2)`, the scalar `A` will have the value 2.
