Further Java Notes
My Matlab notes: Clear Variables: clear all variables >> clear clear a variable >> clear x Set zeros on a variable create zero on matrix 3 x 3 >> x = zeros(3) create zero on matrix 1 x 3 >> x = zeros(1,3) create zero on matrix 0 x 3 >> x = zeros (0,3) set a certain number on a matrix column >> x(:,2) = 5 Matrix concatenation Concat horizontal (sideway) >> a = [2 3] a = 2 3 >> b = [4 5] b = 4 5 >> c = [a,b] c = 2 3 4 5 Concat Vertical >> d = [a;b] d = 2 3 4 5 Display segment for two sequential points for i=1:size(data,1)-1 plot3([data(i,2) data(i+1,2)],[data(i,3) data(i+1,3)], [data(i,4) data(i+1,4)],'b-') end
