What are the resulting dimensions of the following calculations:
If you cannot perform an operation, state why not. Also, if the result is a vector, state whether it is a row vector or column vector.
compute the following:
compute the following: If a quantity cannot be computed, state the reason why.
is a norm (i.e., show that this definition satisfies conditions i) - iv) in Section 4 of the Linear Algebra Handout).
is not a norm (HINT: Find 2 matrices that violate condition v) in Section 4).
