Advertisements Similar questions have been asked already but I still can’t come up with a solution. I have a pandas Dataframe of such a shape: 1 0 0 0 0 1 0 0 0 0 1 0 0 0 0 1 0 0 0 0 -1 0 0 0 0 -1 0 0 0 0… Read More Set diagonal values in a Dataframe
Advertisements Firstly, a number N has to be input, and the matrix is of NxN dimensions then. The diagonal of the matrix has to be all 0, the elements of the matrix above the diagonal have to be from 1 to N diagonally, and the elements under the diagonal need to be filled from -1… Read More Matrix with the diagonal set to 0, and the rest of the elements set from 1 to n (in C)
Advertisements Hello I have this matrix that is (5 x 7) and as you can see the matrix has three-diagonals from repeating numbers I was wondering how to compute this matrix but for (t-2) x t dimension I have this code, but only get the vector (of repeating numbers) in the diagonal (not 3 diagonal)… Read More How to create a multi diagonal matrix in R
Advertisements I have a dataset like this I want to separate "money", "income" and "loan" on separates rows. I mean, I want to get this : My first thought was : replicate the row and then remove extra value to get the desire result. I got this : But I’m stuck to remove value in… Read More Remove a specific duplicate values and keep diagonal
Advertisements Having a 2D numpy array with shape (i,j), where each column is a vector with i entries, how can I obtain a 3D numpy array with shape (j, i, i) where each j corresponds to a diagonal matrix with each vector on its diagonal without using for loops? For example, having the 2D array… Read More How to turn a 2D array into a 3D diagonal matrix with numpy
