The numpy.eye() returns a 2-D array with 1’s as the diagonal and 0’s elsewhere. Here, the 1st parameter means the "Number of rows in the output" i.e. 4 means 4x4 array. The 2nd parameter is the number of columns in the output. If None, defaults to the 1st parameter i.e. 4x4 here. The 3rd parameter i.e. K is the Index of the diagonal: 0 (the default) refers to the main diagonal, a positive value refers to an upper diagonal, and a negative value to a lower diagonal. We have set the lower diagonal with a negative value K.The function eye() ... Read More

The numpy.eye() returns a 2-D array with 1’s as the diagonal and 0’s elsewhere. Here, the 1st parameter means the "Number of rows in the output" i.e. 4 means 4x4 array. The 2nd parameter is the number of columns in the output.The function eye() returns an array where all elements are equal to zero, except for the k-th diagonal, whose values are equal to one. The dtype is the data-type of the returned array. The order suggests whether the output should be stored in row-major (C-style) or column-major (Fortran-style) order in memory.The like parameter is a reference object to allow ... Read More

To return a new array with the same shape and type as a given array, use the numpy.empty_like() method in Python Numpy. It returns the array of uninitialized (arbitrary) data with the same shape and type as prototype. The 1st parameter here is the shape and data-type of prototype(array-like) that define these same attributes of the returned array. We have set the order using the "order" parameter.The order overrides the memory layout of the result. ‘C’ means C-order, ‘F’ means F-order, ‘A’ means ‘F’ if prototype is Fortran contiguous, ‘C’ otherwise. ‘K’ means match the layout of prototype as closely ...

To return a new Three-Dimensional array, without initializing entries, use the numpy.empty() method in Python Numpy. The 1st parameter is the Shape of the empty array. The order is changed using the "order" parameter. We have set the order to "C" i.e. C-style, that means to store the data in row-major order in memory.The dtype is the desired output data-type for the array, e.g, numpy.int8. Default is numpy.float64. The order suggests whether to store multi-dimensional data in row-major (C-style) or column-major (Fortran-style) order in memory.The function empty() returns an array of uninitialized (arbitrary) data of the given shape, dtype, and ...
