Logic functions¶
Truth value testing¶
| all (a[, axis, out]) | Returns True if all elements evaluate to True. |
| any (a[, axis, out]) | Test whether any elements of an array evaluate to True along an axis. |
Array contents¶
| isfinite (x[, out]) | Returns True for each element that is a finite number. |
| isinf (x[, out]) | Shows which elements of the input are positive or negative infinity. Returns a numpy boolean scalar or array resulting from an element-wise test for positive or negative infinity. |
| isnan (x[, out]) | Returns a numpy boolean scalar or array resulting from an element-wise test for Not a Number (NaN). |
| isneginf (x[, y]) | Return True where x is -infinity, and False otherwise. |
| isposinf (x[, y]) | Shows which elements of the input are positive infinity. |
Array type testing¶
| iscomplex (x) | Return a bool array, True if element is complex (non-zero imaginary part). |
| iscomplexobj (x) | Return True if x is a complex type or an array of complex numbers. |
| isfortran (a) | Returns True if array is arranged in Fortran-order and dimension > 1. |
| isreal (x) | Returns a bool array where True if the corresponding input element is real. |
| isrealobj (x) | Return True if x is not a complex type. |
| isscalar (num) | Returns True if the type of num is a scalar type. |
Logical operations¶
| logical_and (x1, x2[, out]) | Compute the truth value of x1 AND x2 elementwise. |
| logical_or (x1, x2[, out]) | Compute the truth value of x1 OR x2 elementwise. |
| logical_not (x[, out]) | Compute the truth value of NOT x elementwise. |
| logical_xor (x1, x2[, out]) | Compute the truth value of x1 XOR x2 elementwise. |
Comparison¶
| allclose (a, b[, rtol, atol]) | Returns True if two arrays are element-wise equal within a tolerance. |
| array_equal (a1, a2) | True if two arrays have the same shape and elements, False otherwise. |
| array_equiv (a1, a2) | Returns True if input arrays are shape consistent and all elements equal. |
| greater (x1, x2[, out]) | Return (x1 > x2) element-wise. |
| greater_equal (x1, x2[, out]) | Element-wise True if first array is greater or equal than second array. |
| less (x1, x2[, out]) | Returns (x1 < x2) element-wise. |
| less_equal (x1, x2[, out]) | Returns (x1 <= x2) element-wise. |
| equal (x1, x2[, out]) | Returns elementwise x1 == x2 in a bool array. |
| not_equal (x1, x2[, out]) | Return (x1 != x2) element-wise. |
