numpy.expm1(array, out = None, where = True, casting = ‘same_kind’, order = ‘K’, dtype = None) :
This mathematical function helps user to calculate exponential of all the elements subtracting 1 from all the input array elements.
array : [array_like]Input array or object whose elements, we need to test. 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 exponential(all elements of input array) - 1.
Code 1 : Working
Input array : [1, 3, 5] Exponential value of array element : [ 2.71828183 20.08553692 148.4131591 ] (Exponential value of array element) - (1) : [ 1.71828183 19.08553692 147.4131591 ]
Code 2 : Graphical representation
out_array : [ 1.71828183 2.32011692 3.05519997 3.95303242 5.04964746 6.3890561 ]
