%% RSS Levels of 2-D Matrix Along Specified Dimension % Create a matrix where each row is a 100 Hz sinusoid sampled at 1 kHz with % a different amplitude. The amplitude is equal to the row index. % Copyright 2015 The MathWorks, Inc. %% % Compute the RSS levels of the rows specifying the dimension equal to 2 % with the DIM argument. t = 0:0.001:1-0.001; x = (1:4)'*cos(2*pi*100*t); y = rssq(x,2)
