@Carl Love 

My M matrix don't accept any mahematical operations narrow extracting its columns, have you any idea?

The answer is

Error, (in LinearAlgebra:-Column) invalid input: LinearAlgebra:-Column expects its 1st argument, A, to be of type Matrix but received M

First i want to thak you for you answer Dear Carl Love

I didn't solve my problem yet,
In my case i want to plot some columns of m[T] vs others, that's whay i need to convert and print m[T] as a matrix. After convert(m, list) i can't change my curve configurations and axis.

the question now is how to assign convert(m, list) to form a (true) vector or matrix.

Can you help me please?

Thak's.
