' Evaluate the transposed matrix' A transposed matrix is the array you get when you "rotate" a bi-dimensional ' array'' Example' Dim arr(,) As Double = {{0.0, 0.1, 0.2}, {1.0, 1.1, 1.2}}' Dim i, j As Integer' ' print the original matrix' Debug.WriteLine("Original matrix")' For i = 0 To arr.GetUpperBound(0)' For j = 0 To arr.GetUpperBound(1)' Debug.Write(arr(i, j) & " - ")' Next' Debug.WriteLine("")' Next' ' transpose the matrix and print it' Dim arr2(,) As Double = TransposeMatrix(arr)' Debug.WriteLine("Transposed matrix")' For i = 0 To arr2.GetUpperBound(0)' For j = 0 To arr2.GetUpperBound(1)' Debug.Write(arr2(i, j) & " - ")' Next' Debug.WriteLine("")' NextFunction TransposeMatrix(ByVal arr(,) As Double) As Double(,) Dim startRow As Integer, startCol As Integer Dim endRow As Integer, endCol As Integer Dim row As Integer, col As Integer ' get size of original matrix startRow = arr.GetLowerBound(0) endRow = arr.GetUpperBound(0) startCol = arr.GetLowerBound(1) endCol = arr.GetUpperBound(1) ' prepare the result matrix Dim res(endCol, endRow) As Double ' transpose the matrix For row = startRow To endRow For col = startCol To endCol res(col, row) = arr.GetValue(row, col) Next Next ' return the transposed result Return resEnd Function
