WebThe transpose (reversing rows and columns) is perhaps the simplest method of reshaping a dataset. Use the t () function to transpose a matrix or a data frame. In the latter case, row names become variable (column) names. An example is presented in the next listing.

WebThese operations all work on entire matrices. I am missing a section on basic operations on matrix rows / columns. For example: Extracting a row from a matrix. Inserting a row into a matrix. Adding two rows within a matrix together. Swapping two rows. Multiplying a row with a number. And similar for columns. WebAxis or axes along which to flip over. The default, axis=None, will flip over all of the axes of the input array. If axis is negative it counts from the last to the first axis. If axis is a tuple of ints, flipping is performed on all of the axes specified in the tuple. Changed in version 1.15.0: None and tuples of axes are supported Returns:
WebGiven an m x ninteger matrix matrix, if an element is 0, set its entire row and column to 0's. You must do it in place. Example 1: Input:matrix = [[1,1,1],[1,0,1],[1,1,1]] Output:[[1,0,1],[0,0,0],[1,0,1]] Example 2: Input:matrix = [[0,1,2,0],[3,4,5,2],[1,3,1,5]] Output:[[0,0,0,0],[0,4,5,0],[0,3,1,0]] Constraints: m == matrix.length
