Programming with MATLAB-Quiz 2 1. Create the following vectors and variables in Matlab, (80 pts) u= [-1,9,3,-35,10,-18] 2.5 w=1-0.7 10 14 11, Ill. u : A random row vector with 5 elements in the interval 1-17, 71 . P5×40 =11 1 1 V. g: A vector of 13 elements that are evenly spaced between |-105,95 VI, k= [15, 5,-5,-15,-25, ,-451] VII, E 12-9-1 10 11 -14 0.01 [1x104 1.1x104 1.2x10" 4.3x10. 0.04 33.0 0.07 32.0.. 1.0 1.0 ... VIll. Q=134.0 2. Find the answer to the folowing questions (80 pts) Eliminate the last element in v and find the vector y that is the elements of w divided by elements of v ll. Solve R = u× P and L-Prxw Il. Find all elements in vector k that are negative numbers and are greater than-100. IV, Change the element "-9" in E to "49" V. How many elements in Q are between 0.0002 and 0.602 Solve Z = Ex :/O (show the first column)
