12R-CF 11/28/2011 ENGE1114-HW 13 Lubnow, Brian 1/2 PROBLEM STATEMENT: HW 13 Problem 1, learn to create and use function files in MatLab. SOLUTION: K = 0; MIN = 0; MAX = 1000; sumnum = 0; m = 0; Tdif = 0; vn = randi([10,100]); for K = 1:1:vn C = randi(1000); sumnum = sumnum + C; if v > MAX MAX = C; else if C < MIN MIN = C; end V(K) = C; end end avgnum = sumnum / vn; for m = 1:1:vn dif(m)=(V(m)-avgnum)^2; Tdif = dif(m) + Tdif; end div = Tdif/ (vn-1); dev = sqrt(div); fprintf( 'The number of values in the vector is: %.0f\n' , vn) fprintf( 'The average number is: %.0f\n' , avgnum) fprintf( 'The standard deviation of the numbers is: %.2f\n' , dev) fprintf( 'The maximum number is: %.0f\n' , max) fprintf( 'The minimum number is: %.0f\n' , min)
