Using basic programming (for loops, while loops, and if statements), write two matlab functions, both taking as input:
- dimension n;
- n x n matrix a;
- n x n matrix b;
-n × 1 vector x.
have the first function compute abx through (ab)x and the second compute abx through a(bx). have both output:
- the number of flops used.
(a) print out or write out the first function.
(b) print out or write out the second function.
(c) apply both your functions to the case with random matrices and vectors for n = 100 and print out or write out the results. do the same for 200 x 200, 400 x 400, and 800 x 800. which approach of computing abx is faster?

Consider the following statements: #include #include class temporary { private: string description; double first; double second; public: temporary(string = "", double = 0.0, double = 0.0); void set(string, double, double); double manipulate(); void get(string& , double& , double& ); void setdescription(string); void setfirst(double); void setsecond(double); }; write the definition of the member function set() so that the instance variables are set according to the parameters. write the definition of the constructor so that it initializes the instance variables using the function set() write the definition of the member function manipulate() that returns a decimal number (double) as follows: if the value of description is "rectangle", it returns first * second if the value of description is "circle" it returns the area of a circle with radius first if the value of description is "cylinder" it returns the volume of a cylinder with radius first and height second. hint: the volume of a cylinder is simply the area of the circle at the base times the height. if the value of description is "sphere" it returns the volume of the sphere with radius first. otherwise it returns -1.0;
