Enter the following matrix in matlab. a =   −1 3 −4 −2 10 −16 −4 10 −10   (a) determine elementary matrices e1, e2, e3 of type iii such that e3e2e1a = u with u an upper triangular matrix. the matrix e1 should turn the element in position (2,1) into a 0. enter this matrix in matlab as e1 using commands similar to the ones in example 1. the matrix e2 should turn the element in position (3,1) into a zero. enter this matrix in matlab as e2. note that to zero out the entries in column 1, you need to add or subtract a multiple of row 1. once you have found the matrices e1 and e2, compute the product e2e1a in matlab. use format rat so that the entries will be given as fractions. based on the result, determine the matrix e3 that turns the element in position (3,2) into a zero. enter this matrix as e3 in matlab and compute u=e3*e2*e1*a.

This assignment continues work on the online booking facility introduced at the end of chapter- 10. the work will be continued in the assignments for chapters 14 and 15 (a) assume that you will produce your online booking facility using an agile approach. i. suggest the kind of user research you would like to conduct for your product before iteration cycles begin. ii prioritize the requirements for your product according to business value, i.e which requirements are likely to provide the greatest business benefit, and sketch out the ux design work you would expect to undertake during the first four iteration cycles, i.e. cycle 0, and cycles 1 to 3. (b) using one of the mockup tools introduced above, generate a mockup of your product's landing page, as developed in the assignment for chapter-11 (c) using one of the patterns websites listed previously, identify suitable interaction patterns for elements of your product, and develop a software-based prototype that incorporates all the feedback and the results of the user experience mapping achieved at the end of chapter-11. if you do not have experience in using any of these, create a few html web pages to represent the basic structure of your website
