WebJan 16, 2014 · Always O(n^2) - or rather O(n x m). You cannot jump over it. But if you know that matrix is sparse (only a few elements have nonzero values), you can store only values that are non zero and matrix size. Then consider using hashing over storing whole matrix - generally create hash which maps a row number to a nested hash.
WebOct 19, 2015 · How is it possible to expand a quadratic - let's say NxN - matrix to a bigger on like a (N+k)x(N+k) matrix? It's really all about resizing the matrix and filling the missing rows/columns with zeros such that not dimension mismatch occurs. WebSep 17, 2024 · The matrix \[E = \left[ \begin{array}{rr} 1 & 0 \\ -3 & 1 \end{array} \right]\nonumber \] is the elementary matrix obtained from adding \(-3\) times the first row to the third row. You may construct an elementary matrix from any row operation, but remember that you can only apply one operation. Consider the following definition.
WebSep 15, 2024 · Given an integer K and a matrix of N rows and M columns, the task is to find the minimum number of operations required to make all the elements of the matrix equal. In a single operation, K can be added to or subtracted from any element of the matrix. Print -1 if it is impossible to do so. WebA square matrix in which all the elements below the diagonal are zero is known as the upper triangular matrix.
