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

Now you’re on your own. include a short summary of this section with plots in your lab report. write a matlab script file to do steps (a) through (d) below. include a listing of the script file with your report. 1 the soundsc(xx, fs) function requires two arguments: the first one (xx) contains the vector of data to be played, the second argument (fs) is the sampling rate for playing the samples. in addition, soundsc(xx, fs) does automatic scaling and then calls sound(xx, fs) to actually play the signal. mcclellan, schafer, and yoder, dsp first, 2e, isbn 0-13-065562-7. prentice hall, upper saddle river, nj 07458. c 2015 pearson education, inc. 4 mcclellan, schafer and yoder, signal processing first. prentice hall, upper saddle river, new jersey, 2003. c 2003 prentice hall. (a) generate a time vector (tt) to cover a range of t that will exhibit approximately two cycles of the 4000 hz sinusoids defined in the next part, part (b). use a definition for tt similar to part 2.2(d). if we use t to denote the period of the sinusoids, define the starting time of the vector tt to be equal to t , and the ending time as ct . then the two cycles will include t d 0. finally, make sure that you have at least 25 samples per period of the sinusoidal wave. in other words, when you use the colon operator to define the time vector, make the increment small enough to generate 25 samples per period. (b) generate two 4000 hz sinusoids with arbitrary amplitude and time-shift. x1.t / d a1 cos.2
