how to accept equations from the user and convert to a matrix?

Please help me. I am writing a code to accept equations from the user and then convert it to a matrix to perform row operations. The purpose is to create a generic code for a system of linear equations. Following is the code .

m = input ('Enter number of unknowns: ');
n = input ('Enter number of equations: ');

syms x y
for j=1:n
    equ(j)= input ('Enter equations: ','s');
end

for j=1:n
    func(j) = evalin(symengine, equ(j));
end

for j=1:n
    [A,B] = equationsToMatrix([func(j)], [x, y])
end

Change

    equ(j)= input ('Enter equations: ','s');

to

    equ(j) = string( input ('Enter equations: ','s') );

This requires R2016b or later.

This change is adjusting for the fact that in MATLAB, input() with the 's' parameter requires a character vector, which will be a vector, and vectors cannot be stored into a single location like equ(j) . The string() call converts the character vector into a string object, and string objects can be stored into a single location like equ(j)
