How do i write a code which can calculate the cross production of two vector ? Both of these two vectors are 1 by 5 vector
At first, i write the code like
a=randn(1,5);
b=randn(1,5);
cross_c=cross(a,b)
or
a=randn(1,5);
b=randn(1,5);
cross_c=cross(a,b,5)
But the window always show me
A and B must be of length 3 in the
dimension in which the cross
product is taken.
How do i write a code which can calculate the cross production of these two 1 by 5 vectors?

Cross products are defined for 3-element vectors only. Maybe you could tell us what your definition of this for 5-element vectors would be. What are you using this for?

If A and B are 5 x 1
null([a;b])
returns a (5 x 3), 3 vectors in R^5 basis of NULL(SPAN(a,b))
