numpy.log1p(arr, out = None, *, where = True, casting = ‘same_kind’, order = ‘K’, dtype = None, ufunc ‘log1p’) :
This mathematical function helps user to calculate natural logarithmic value of x+1 where x belongs to all the input array elements.
array : [array_like]Input array or object. out : [ndarray, optional]Output array with same dimensions as Input array, placed with result. **kwargs : allows you to pass keyword variable length of argument to a function. It is used when we want to handle named argument in a function. where : [array_like, optional]True value means to calculate the universal functions(ufunc) at that position, False value means to leave the value in the output alone.
An array with natural logarithmic value of x + 1; where x belongs to all elements of input array.
Code 1 : Working
Input array : [1, 3, 5] Output array : [ 0.69314718 1.38629436 1.79175947]
Code 2 : Graphical representation
out_array : [ 0.69314718 0.78845736 0.87546874 0.95551145 1.02961942 1.09861229]
