Determines if two expressions are not equal.

NOTEQUAL(val1, val2)

val1 |
- |
A scalar, series, or table. |

val2 |
- |
A scalar, series, or table. |

A scalar, series, or table (containing the value 1 or 0) of the same type as the higher of the two expressions. Integer is the lowest type, Real is next, and Complex is the highest type. If one or both of the expressions is a series, then a series results. The following is a list of type conversion rules:

Integer |
!= |
Real |
yields Real |

Integer |
!= |
Series |
yields Series |

Integer |
!= |
Integer |
yields Integer |

Real |
!= |
Complex |
yields Complex |

Real |
!= |
Series |
yields Series |

Complex |
!= |
Real Series |
yields Complex Series |

String |

String |
yields Integer |

notequal(max(W1), 10.0)

returns a 1 if the maximum value of W1 does not equal 10.0, or 0 if the maximum value of W1 equals 10.0.

notequal({1, 5, 6}, {1, 2, 4})

returns the series {0, 1, 1}.

notequal(a, b) is equivalent to a != b.

NOTEQUAL uses STRCMP for string arguments.
