Two vectors have been defined in the workspace: x = [1 2 3 4 5]: y = [2 4 6 8]; A nested looping structure is used to define a new matrix variable called xy_func as follows: for x_vec = 1:5, for y_vec = 1:4, xy_func(x_vec,y_vec) = x(x_vec) * y(y_vec)^2; end; end; Use a variable tracking table to determine the values in the third row of the xy_func variable.
