a$)$ In a single$-$line, create a matrix named A where the first row are the values $735.$ Using colon notion, initialize the second row to be between $4$ and $7$ with a step size of $1\mathrm{.}5.$ Using the linspace function, initialize the third row to be between $6$ and $10$ where the number of points is $3.$Use colon notation to write a single$-$line to multiply the first row by the third column and assign the result to the variable in matlab
