Thank you so much! It works.

Here is the code I used in SageMath computations.

var('a11,a12,a21,a22,b1,b2')

A = matrix([[a11,a12,b1],[a21,a22,b2]])

A.add_multiple_of_row(1,0,-a21/a11)

pretty_print(A)

The output is as follows.

Is it possible to simplify the entries in the form a/b?

Thanks for your time.

A linear algebra question Is it possible to solve this linear algebra question by SageMath? Given column vectors v1=[1,

Thank you so much. It seems that I'd better type the matrix into the system since I just occasionally use sagemath.

Are you able to give me some reference to read?

Thanks a lot for replying my question.

 \left(\begin{array}{rrr}0 & 1 & 2 \\ 1 & 0 & 3 \\ 4 & -3 & 8 \end{array}\right)

I donot know how to exactly state my question. I gonna give an example.

Step 1. Type in A=matrix([[1,-3,-4,3],[-4,6,-2,3],[-3,7,6,-4]])

Step 2. latex(A) gives the latex code for this matrix.

My question is that given a latex code, is there a way to converts to SageMath code?

I am new to SageMath. As an instructor of math for 5 years, I have many resources prepared in latex code.

So I really wanna converts them to SageMath instead of type it again.

Thank you in advance.
