Use an appropriate command to create the following matrices, $$Do not type the

individual elements explicitly in the command:$$ a$.13579$

$2025303540$

b$.0000$

$86422.$ Use the linspace function to create a row vector named $$Fours$$ with $9$ values that are all

equal to $4.$

$3.$ Create a variable g that is a row vector in which the first element is $3$ and the last element

is $27,$ with an increment of $4$ between the elements $(3,7,11,...,27).$

$4.$ Create a variable h that is a row vector with eight equally spaced elements in which the

first element is $68$ and the last element is $12.$
