April 15th, 2019 - Add Code Add Code Home Source Code A wideband Beamforming MATLAB to write A wideband Beamforming MATLAB to write xz972662 sina com 2016 06 18 01 57 28 A wideband Beamforming MATLAB . 4 2 7. 4, is represented by one block, i. Let selectRows be a logical vector with numel(selectRows) == size(A,1) with true for rows to be kept, and false for rows to be discarded. Here I filter out rows 3 - 5 by telling Matlab which rows and which columns (all of them in our case) to keep. Step 1 is to find those rows (either the rows to keep or the rows to filter, it doesn't matter): Try that in the command line without the ; and you'll see it sums along the rows (the 2 in the sum argument) and chooses only those that are greater than 10 by creating a vector of logicals (Matlab's boolean type). Choose a web site to get translated content where available and see local events and The syntax for sorting matrix in Matlab X = sort (Y) X = sort (Y, dimension) X = sort (Y, direction) Description: X = sort (Y) is used to sort the elements of Y in the ascending order.
