Logic functions

Truth value testing

Array contents

isfinite(x[, out]) Test element-wise for finiteness (not infinity or not Not a Number).
isinf(x[, out]) Test element-wise for positive or negative infinity.
isnan(x[, out]) Test element-wise for NaN and return result as a boolean array.

Array type testing

Logical operations

logical_and(x1, x2[, out]) Compute the truth value of x1 AND x2 element-wise.
logical_or(x1, x2[, out]) Compute the truth value of x1 OR x2 element-wise.
logical_not(x[, out]) Compute the truth value of NOT x element-wise.
logical_xor(x1, x2[, out]) Compute the truth value of x1 XOR x2, element-wise.

Comparison

greater(x1, x2[, out]) Return the truth value of (x1 > x2) element-wise.
greater_equal(x1, x2[, out]) Return the truth value of (x1 >= x2) element-wise.
less(x1, x2[, out]) Return the truth value of (x1 < x2) element-wise.
less_equal(x1, x2[, out]) Return the truth value of (x1 =< x2) element-wise.
equal(x1, x2[, out]) Return (x1 == x2) element-wise.
not_equal(x1, x2[, out]) Return (x1 != x2) element-wise.
