Recall that if a is an m × n matrix and b is a p × q matrix, then the product c = ab is defined if and only if n = p, in which case c is an m × q matrix. (a) write a function m-file that takes as input two matrices a and b, and as output produces the product by columns of the two matrix. for instance, if a is 3 × 4 and b is 4 × 5, the product is given by the matrix c = [a*b(: ,1), a*b(: ,2), a*b(: ,3), a*b(: ,4), a*b(: ,5)] this content is protected and may not be shared, uploaded, sold or distributed 2019 v3 copyright@ school of mathematical and statistical sciences, arizona state university 8 the function file should work for any dimension of a and b and it should perform a check to see if the dimensions match (hint: use a for loop to define each column of c). call the file columnproduct. m. test your function on a random 3×2 matrix a and a random 2×5 matrix b . compare the output with a*b. repeat with 5 × 3 and 3 × 4 matrices and with 5 × 3 and 4 × 3 matrices. use the command rand to generate the random matrices for testing. include in your lab report the function m-file and the output obtained by running it

given the options, i would say your best bet is c. the modem supports up to 56 kbps, which is too low for video streaming. dial up modems use actual phone lines, which only can go up to 56 kbps as that's more than sufficient for traditional phone calls. this is also the reason why when a dial-up modem connects, you hear all those sounds. it's literally using the phone line to establish a connection.

a  social news website  is an  internet  website  that features  user-posted stories. such stories are ranked based on popularity, as voted on by other users of the site or by website administrators. users typically comment online on the news posts and these comments may also be ranked in popularity. since their emergence with the birth of  web 2.0, social news sites have been used to link many types of information, including news, humor, support, and discussion. all such websites allow the users to submit content and each site differs in how the content is moderated. on the  slashdot  and  fark  websites,  administrators  decide which articles are selected for the front page. on  reddit  and  digg, the articles that get the most votes from the community of users will make it to the front page. many social news websites also feature an online comment system, where users discuss the issues raised in an article. some of these sites have also applied their voting system to the comments, so that the most popular comments are displayed first. some social news websites also have a  social networking  function, in that users can set up a user profile and follow other users' online activity on the website.
