### Latex and SageMath

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.
