How to create a vector space?

I'm trying to create a vector space

I copied the example from

http://www.mathworks.com/help/symbolic/mupad_ref/linalg-basis.html

The following code is from example 1

MatQ := Dom::Matrix(Dom::Rational):
v1 := MatQ([3, -2]): 
v2 := MatQ([1, 0]): 
v3 := MatQ([5, -3]):
linalg::basis([v1, v2, v3])

I received the following message after typing in the code above:

"Undefined function 'MatQ' for input arguments of type 'char'."

I also tried it without using the Dom::Matrix

v1 = [-pi,pi];
linalg::basis([v1])

I received the following error message:

"linalg::basis([v1]) | Error: Unexpected MATLAB operator."

When I use:

which linalg::basis

I receive the following message:

"'linalg::basis' not found."

Does that mean I'm missing a toolbox?
