Problem 1. Implement a class Matrix that creates matrix objects with attributes 1. colsp -column space of the Mat rix object, as a list of columns (also lists) 2. rowsp -row space of the Mat rix object, as a list of rows (also lists) The constructor takes a list of rows as an argument, and constructs the column space from this rowspace. If a list is not provided, the parameter defaults to an empty list.
You must implement the following methods in the Matrix class: Setters - set_col(self, j, u) - changes the j-th column to be the list u. If u is not the same length as the existing columns, then the method raises a ValueError with the message Incompatible column length. - set_row(self, i,v) - changes the i-th row to be the list v. If v is not the same length as the existing rows, then method raises a ValueError with the message Incompatible row length.
- set_entry (self, i, j,x) - changes the existing aij entry in the matrix to x. Getters - get_col(self, j) - returns the j-th column as a list. - get_row(self, i) - returns the i-th row as a list v. - get_entry (self, i,j ) - returns the existing aij​ entry in the matrix. - col_space (self) - returns the list of vectors that make up the column space of the matrix object - row_space(self) - returns the list of vectors that make up the row space of the matrix object - get_diag(self, k) - returns the k-th diagonal of a matrix where k=0 returns the main diagonal, k>0 returns the diagonal beginning at a 1(k+1) , and k<0 returns the diagonal beginning at a (−k+1)1​ . e.g. get_diag (1) for an n×n matrix returns [a12,a 23​ ,a 34,…,a (n−1)n​ ] - _str__(self) - returns a formatted string representing the matrix entries as
