hey everyone and welcome back well this
will be a super quick lesson and it's
intended to answer one question and one
question only do matrices recycle yes
absolutely matrices are very responsible
and just like vectors and other
operations matrices recycle
do you remember what recycling is well
in the context of matrices if you
specify dimensions that cannot be filled
up by what you have in the vectors your
bending or binding or will recycle the
vectors so your matrix is complete for
example if I passed the vector from one
to ten in the matrix function and made
it explicit that I want my matrix to
contain four rows and four columns
effectively needing 16 values are will
recognize that my vector is too short
for the matrix and it will repeat it
until all 16 value spots hold the value
as you see in this particular case are
also issues a warning that 10 is not a
multiple of the number of rows but that
isn't usually consequential in any of
the cases it does that so don't worry
about it so the moral of the story here
well be aware that recycling will happen
if necessary in some matrix operations
that's it that is the whole lesson
thanks for watching and catch you in the
next one
