Question

Q1: if y= [1,2,3,4,6,5,4,3,8,9,7,6,5,4,3,2], then a) replace the first three elements of vector y with its minimum value. b) reshape this vector into a 4 x 4 matrix. Q2: What are the output of the following: 1:- >> x= [3 4 5 1 2 3 7 8 9]; >> x' 2:- >> x= [3 4 5 1 2 3 7 8 9]; >> diag (x) 3:- >> x= [3 4 5 1 2 3 7 8 9]; >>tril(x) 4:- >> x= [3 4 5 1 2 3 7 8 9]; >> numel (x) 5:- >> x= [3 4 5 1 2 3 7 8 9]; >> x (1,:)
