What happens if adding the step value would go beyond the range specified by the last? (first:step:last)

For example:

1:2:6

Matlab will show an error message and abort the operation

It will stop at the largest number below the last: 1 3 5

It will create an element larger than the last value: 1 3 5 7

It will create an element with the last value: 1 3 5 6

How can you use the colon operator to generate the vector shown below?

9  7  5  3  1

>> 1 : 2 : 9

>> 9 :-2 : 1

>> 9 : 1 :-2

>> 9 : 2 : 1

>> 1 : 9 :-2

What is true about Matrices below?

Vectors and scalars are special cases of matrices.

A vector can only be a row.

A scalar (one value) has dimensions "1 x n"

The dimensions of a matrix are "c x r", where "c" is the number of columns and "r"is the number of rows

If a vector has "n" elements, a row vector would have dimensions "1 x n"

How many elements would be in the vectors created by the following expression?

linspace(3,2000)
