$1.$ You are given a matrix $uof$ size $4x1$

$u=[N1,N1+0\mathrm{.}1$;$N1**2$;$N1+3]in$ MATLAB, and a second matrix $vof$ size $4x1,$

$v=[N1-0\mathrm{.}2,N1**0\mathrm{.}1$;$N1-0\mathrm{.}001$;$N1+1\mathrm{.}2]in$ MATLAB.

$T$ denotes transpose $in$ MATLAB

inv denotes inverse $of$ a matrix $in$ MATLAB.

$a-W=u(v)$

$b-W=v(v^T)$

$c-W=(v^{-1})(v)$

$d-W=v(u^T)$

$e-W=2u(v^T)$

$f-W=u(v^{-1})$

NOTE THAT : N$1=8.$
