To integrate a Hermite series, use the hermite.hermint() method in Python. The 1st parameter, c is an array of Hermite series coefficients. If c is multidimensional the different axis correspond to different variables with the degree in each axis given by the corresponding index. The 2nd parameter, m is an order of integration, must be positive. (Default: 1). The 3rd parameter, k is an integration constant(s). The value of the first integral at lbnd is the first value in the list, the value of the second integral at lbnd is the second value, etc. If k == [] (the default), ... Read More
To generate a pseudo Vandermonde matrix of the Laguerre polynomial, use the laguerre.lagvander2d() in Python Numpy. The method returns the pseudo-Vandermonde matrix. The shape of the returned matrix is x.shape + (deg + 1, ), where The last index is the degree of the corresponding Laguerre polynomial. The dtype will be the same as the converted x.The parameter, x, y returns an Array of points. The dtype is converted to float64 or complex128 depending on whether any of the elements are complex. If x is scalar it is converted to a 1-D array. The parameter, deg is a list of ... Read More
To differentiate a Hermite series, use the hermite.hermder() method in Python. The 1st parameter, c is an array of Hermite series coefficients. If c is multidimensional the different axis correspond to different variables with the degree in each axis given by the corresponding index.The 2nd parameter, m is the number of derivatives taken, must be non-negative. (Default: 1). The 3rd parameter, scl is a scalar. Each differentiation is multiplied by scl. The end result is multiplication by scl**m. This is for use in a linear change of variable. (Default: 1). The 4th parameter, axis is an Axis over which the ... Read More

To integrate a Laguerre series, use the laguerre.lagint() method in Python. The method returns the Laguerre series coefficients c integrated m times from lbnd along axis. At each iteration the resulting series is multiplied by scl and an integration constant, k, is added. The scaling factor is for use in a linear change of variable.The 1st parameter, c is an array of Laguerre series coefficients.

Suppose, we are given a grid of dimensions h x w. There are two types of cells in the grid, white and black cells. White cells are represented by '.', whereas black cells are represented by '#'. Now the grid has multiple black cells in it that form a polygon. We have to find out the number of sides that the polygon has. It is to be noted, that the outermost cells of the grid are always white.So, if the input is like h = 4, w = 4, grid = {"....", ".##.", ".##.", "...."}, then the output will be ... Read More
Suppose, there are two points in a 2D plane a and b that have the coordinates (x1, y1) and (x2, y2) respectively. Currently, we are at point 'a' and we can move at a distance of 1 either vertically or horizontally. We move to point b from point a, then get back to point a, and we go to point b again. It is not allowed to move through the same points more than once except the points a and b. We have to find out the moves we will make in this whole trip, and output it. If we ... Read More
Suppose, we are playing a video game where the protagonist uses knives to defeat his enemies. The protagonist can use the knife for slashing the enemy or he can throw it towards the enemy. If the protagonist throws a knife, that cannot be retrieved again. The damage dealt by knife i is given in the array 'knives' where each element is of the form {slash, throw}. 'Slash' means the damage done to an enemy by slashing them with that knife and 'throw' means damage done to them by throwing that particular knife. Slashing can be done unlimited times, but a ...
