Unformatted text preview: A=rand(3,5) would create a 3 x 5 matrix of random numbers between 0 an 1. To generate a uniform distribution of random numbers on a specified interval [a,b], multiply the output of rand by (b-a) then add a. 14. Assume the following definitions: m=[1 2 3;-4 5 6;7 -8 9] ; b=[10 11 12]; c=[14;15;16] ; i=1:3 (a) Show the matrix m and vectors b and c created by the above statements. m = 1 2 3 4 5 6 7 -8 9 b = 10 11 12 c = 14 15 16...

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
