Lazy Functions

The next functions can be used for computing with any of NDArray, C2Array, NDField and LazyExpr.

Their result is always a LazyExpr instance, which can be evaluated (with compute or __getitem__) to get the actual values of the computation.

abs	Calculate the absolute value element-wise.
arcsin	Compute the inverse sine, element-wise.
arccos	Compute the inverse cosine, element-wise.
arctan	Compute the inverse tangent, element-wise.
arctan2	Compute the element-wise arc tangent of ndarr1 / ndarr2 choosing the quadrant correctly.
arcsinh	Compute the inverse hyperbolic sine, element-wise.
arccosh	Compute the inverse hyperbolic cosine, element-wise.
arctanh	Compute the inverse hyperbolic tangent, element-wise.
sin	Compute the trigonometric sine, element-wise.
cos	Trigonometric cosine, element-wise.
tan	Compute the trigonometric tangent, element-wise.
sinh	Hyperbolic sine, element-wise.
cosh	Compute the hyperbolic cosine, element-wise.
tanh	Compute the hyperbolic tangent, element-wise.
exp	Calculate the exponential of all elements in the input array.
expm1	Calculate exp(ndarr) - 1 for all elements in the array.
log	Compute the natural logarithm, element-wise.
log10	Return the base 10 logarithm of the input array, element-wise.
log1p	Return the natural logarithm of one plus the input array, element-wise.
sqrt	Return the non-negative square-root of an array, element-wise.
conj	Return the complex conjugate, element-wise.
real	Return the real part of the complex array, element-wise.
imag	Return the imaginary part of the complex array, element-wise.
contains	Check if the array contains a specified value.
where	Return elements chosen from x or y depending on condition.
