Write an expression using linspace that will result in the same

as $1$: $0\mathrm{.}5$: $3$

$2.(5)$ Create two row vector variables. Concatenate them together

to create a new row vector variable.

$3.(5)$ Generate a $23$ matrix of random

$$ In real numbers, each in the range $(0,1)$

$$ In real numbers, each in the range $(0,5)$

$$ In integers, each in the inclusive range from $10$ to $50$

$4.(10)$ Create variables for these two matrices:

$=$ $$123$

$416+$

$=$ $$241$

$130+$
