Matrix Column Mathematica

Is there an efficient way to do this.

Matrix column mathematica. In mathematics a matrix plural matrices is a rectangular array or table of numbers symbols or expressions arranged in rows and columns. The wolfram language has many matrix operations that support operations such as building computing and visualizing matrices. It also has a rich language for picking out parts of matrices and assigning new values to them. Tableheadings is an option for tableform and matrixform that gives the labels to be printed for entries in each dimension of a table or matrix.

A matrix can be entered directly with notation. Displaystyle begin bmatrix 1 9 13 20 5 6 end bmatrix. Mathematica stack exchange is a question and answer site for users of wolfram mathematica. I see insert to add.
