what is the difference between a vector and a matrix?

Answer 1

[Matz Johansson Bergström]

A matrix is simply a rectangular array of numbers and a vector is a row (or column) of a matrix.

Read more about the practical details in the documentation Matrices and arrays/vectors.

Also, read some theory in Wikipedia on Matrix (mathematics).

The wiki link says "Bad title"

Another link http://en.wikipedia.org/wiki/Matrix_(mathematics)

[Matz Johansson Bergström]

Well spotted. The parentheses in the wiki URL was coded wrong. Fixed it now.

Answer 2

[mntaser salem]

vector is one dimension array such a=[1 2 3 4 5], but matrix is more than one dimension array such 2*2 matrix b =[ 2 4 6 8 ] , and has some of operation.

[David Young]

I think you mean b = [2 4; 6 8]

[JohnS]

From the info I gathered it seems that a matrix can be one dimensional or two, whereas a vector is one dimensional e.g a row or column vector. Thoughts? Gathered this based on link from per isakson.

Answer 3

[Hayden Wineck]

I had the same question also, thanks for the help.

Answer 4

[Yared Bekele]

Matrix can be one dimesional or more than one, but vector is only one dimesionsl (i.e row vector, column vector). All vectors are matrix, but not all matrix are vectors.
