I want to reduce a matrix contain variable m to echelon form or reduced row echelon form :
A = [1,2;3,m] i.e
The answer should be [1,2; 0, (m-6)]
I try rref(A) in matlab but it reduce without variable m
Thanks for your help!!!

I understand that you want to calculate the reduced row echelon form of an input matrix which consist of unassigned variables. I assume that “rref” method returned an error, when you passed your matrix.
MATLAB provides “rref” method to calculate reduced row echelon form of any matrix that has numeric entries. If we use a variable that is not assigned to a numeric value in the input matrix, MATLAB will throw an error, “Unrecognized function or variable”. Hence, we cannot calculate reduced row echelon form a matrix which has a variable that is not assigned a value.
For more information, kindly follow the documentation link provided below:

Hi
Try declaring m as a symbolic variable and applying rref again. Please also refer to row echelon documentation.
