Question

I need help with how to "Create a column vector from 15 to -25 with a step size of 5"

Answer 1

Your column vector is:

`\left[\begin{array}{c}15&10&5&0&-5&-10&-15&-20&-25\end{array}\right]`

Explanation:

The first step to solve your problem is knowing what is a column vector:

A column vector is a matrix that only has one column, and multiple rows.

The problem wants the vector to range from 15 to -25.

It means that the biggest value in the vector is 15, and the smallest is -25. Since it is from 15 to -25, the first element of your column vector is 15, and the last element is -25.

With a step size of 5

At each element, you decrease 5. So you have: 15,10,..,-20,-25.

The vector is:

`\left[\begin{array}{c}15&10&5&0&-5&-10&-15&-20&-25\end{array}\right]`
