P1. Write a MATLAB function with inputs • m and n, two positive integers, • a matrix A of size m × n, • a vector x of size n × 1, and which outputs the product vector A × x (note that the size of this vector should be m × 1). Your code should check that the sizes of the inputs are right and then do the multiplication using two nested "for" loops. a) How many floating point operations (additions and multiplications) does the code use? Find a formula in terms of m and n. b) Run the code with n = 100, m = 100, and inputs A =rand(m, n) and x =rand(n, 1). Modify the function by introducing a new output variable, op count, which initializes to 0 outside of the nested for loops (just like we did with product in class) and is incremented inside the innermost of the for loops by the number of operations done to update product. (We will do an example of this on Wednesday.) Output op count as well as product. Repeat the experiment for m = 200, n = 100; m = 100, n = 200; and m = n = 200. Do the ratios of the new op count outputs to the old one you got for m = n = 100 confirm the floating point operation formula you found in part a)?

the printer can be used in a both wired and wireless network, only one of the connection methods can be used at one time when the wireless setting is enabled, the wired (ethernet) setting is disabled.

but first you need to

`connect the cord to your computer

`open settings app from the start menu

`click devices

`than click add printer or scanner

and than you should be able to do it from there, if not let me know i can you! : )

we can all learn from our past mistakes because we all have different ways of learning different types of techniques. my way may or may not another classmate remember and have the repetition to acknowledge such standard. such as remembering acronyms. using abbreviations to us remember keep things in order in our memory. this us figure out what comes next in the sequence. if so, what we have is a sentence of just letters all in caps. we either know the meaning or have no idea what it stands for. most of the time we know the meaning and context. but most of us who don't know, should learn by having a quick glance at what needs to be remembered. such as repetition in the memory for acronyms. one way that me, is the fact that i'm always doing math and english assignments. so we have to remember specific meanings such as soapstone for documents, such as citing correctly. or pemdas for doing the equations correctly, even if it's the super long way. this works for everyone. you just have to find what works for you by practicing and repetition daily.
