M Library Functions


To use M library functions, first load them, for example, in M: load cond det
or on the command-line: m cond.m det.m

N		null space, B = N(A)
charpoly	characteristic polynomial
chol		Cholesky decomposition, G = chol(A)
cond		condition number in 2-norm, r = cond(A)
det		determinant, r = det(A)
fact		factorial, r = fact(n)
fib		fib(n) prints the Fibbonaci sequence up to n
integrate	integrate function over an interval
linear		linear scale of n points, X = linear(xmin,xmax,n)
lu		LU reduction, lu(A,L,U)
lup		LU reduction with pivoting, lup(A,L,U,p)
norm1		1-norm, r = norm1(A)
norm2		2-norm, r = norm2(A)
norminf		infinite-norm, r = norminf(A)
pinv		pseudo-inverse, B = pinv(A)
polymul		polynomial multiplication
polyval		polynomial evaluation
qroots		quadratic roots, R = qroots(a,b,c)
qrp		QR decomposition with pivoting, r = qrp(A,Q,R,p)
rref		reduced row echelon form, R = rref(A)
solve		solve LUx=b, x = solve(L,U,b)
