Bad argument type, DET(M9)/M8(2,1) in App
eg1. how([1,4,3,2,1,4,4])--> Error: Bad argument type, M0(B,A):=-DET(M9)/M8(2,1) cant be executed.

eg2. how([1,4,k,2,1,4,4])-> expecting [1,k,1,4] into M0 but Error: Bad argument type

Code:

#pragma mode( separator(.,;) integer(h32) )
exc();
dett();
#cas
how(den):= //"Error: Bad argument type if variable say k is insert into the vector den"
BEGIN
n:=length(den);
m:=length(den);
nx:=simplify(poly2symb(den));
IF even(n-1) THEN rw:=((n-1)/2)+1; ELSE rw:=(n)/2 END;
M0:=makemat(n,rw);
c:=0;
WHILE n>0 DO
    a:=1;L1:={};c:=c+1;
    IF n==0 THEN       
       L1(a):=coeff(nx,n); 
       

    ELSE
       nl:=n-1;
       FOR j FROM c TO length(den) STEP 2 DO
           L1(a):=coeff(nx,x,nl); // "Error: Bad argument type"
           a:=a+1;
           nl:=nl-2;
       END;
         
    END;
    L2(n):=length(L1);
    FOR j FROM 1 TO length(L1) DO
        M0(c,j):=L1(j);
    END;
n:=n-1;
END;
hw:=M0;
exc();
END;
#end


#cas  
exc()
BEGIN
FOR j FROM 1 TO m-2 DO
    k:=j+1;
    B:=j;
    M8:=subMat(M0,j,1..rw,k,1..rw);
    dett();
END;
END;
#end

#cas 
dett()
BEGIN
//M9:=subMat(M8,1,1,2,2);
M9:=matrix(2,2);
B:=B+2;
A:=1;
    FOR j FROM 2 TO rw DO
        M9(1,1):=M8(1,1);
        M9(2,1):=M8(2,1);
        M9(1,2):=M8(1,j);
        M9(2,2):=M8(2,j);    
        M0(B,A):=-DET(M9)/M8(2,1); //"Error: Bad argument type"
        A:=A+1;
    END;
END;
#end
