Question
Which of the following operations are defined and which are not defined? Explain briefly why or why not (it may help to preform these operations when possible).i) A + 5I
ii) |Ab|
iii) (b^TA)^T
iv) b^T + b
v) b^Tb
vi) b*b^T
where T is the transposes of vector b or matrix A. I is the identity matrix
Please help!! Which of the following operations are defined and which are not defined? Explain briefly why or why not (it may help to preform these operations when possible).
i) A + 5I
ii) |Ab|
iii) (b^TA)^T
iv) b^T + b
v) b^Tb
vi) b*b^T
where T is the transposes of vector b or matrix A. I is the identity matrix
Please help!!
Explanation / Answer
i) A + 5I will be defined
ii) |Ab| not defined why because b is vector and A is matrix.
iii) (b^TA)^T not defined why because vector cant transpose.
iv) b^T + b not defined why because vector cant transpose.
v) b^Tb not defined why because vector cant transpose.
vi) b*b^T not defined why because vector cant transpose.
