Write an m-file which will use a random number generator to determine the following:

a) the number of iterations it takes for the random numbers to add up to at least 20

b) the number of iterations it takes before a number between 0.8 and 0.85 is produced

c) the number of iterations it takes for the product of two random numbers to produce a number less than 1e-5

Ryan is working on the layout of her web page. she needs to figure out where her header, navigation bar, text, and images should go. what technique can her?

Using least squares fitting, you are to fit the data sets to the following models and solve for the parameters ai , where i is the index of the parameter. the input/output data for the systems are linked in the bblearn site. for each of the systems use matlab to plot the supplied data vs. the model fit on one plot. include your code in the solutions. (a) linear fit "lineardata. mat" y=a1x^3 + a2x^2 + a3x + a4 (b) plant fit "plantdata. mat g(s) = a1/(s + a2)

Consider a direct-mapped cache with 216 words in main memory. the cache has 16 blocks of 8 words each. it is a word-addressable computer (rather than a byte-addressable computer which we normally discuss). (a) how many blocks of main memory are there? (b) what is the format of a memory address as seen by the cache, that is, what are the sizes of the tag, cache block, and block offset fields (if they apply)? (c) to which cache block will the memory reference db6316 map?
