Fibonacci Triangle Matrices

[Eddie W. Shore]

Here's an alternate code for Fibonacci Triangle Matrices. The row command has been eliminated and I used a second For loop in its place.

Code:

EXPORT FIBMATALT(n)
BEGIN
// 2018-12-23 EWS
// Fibonacci Matrix Alternate
// matrix form
// This version does not have the
// row function.
LOCAL M1,k,j;
M1:=MAKEMAT(0,n+1,n+1);
M1(1,1):=1;
M1(2,1):=1;
M1(2,2):=1;
FOR k FROM 3 TO n+1 DO
FOR j FROM 1 TO n DO
M1(k,j):=M1(k-2,j)+M1(k-1,j);
END;
M1(k,k):=M1(k-1,k-1)+M1(k-2,k-2);
END;
RETURN M1;
END;
