matlab norm(h) command in R: sqrt(sum(h^2)) - use in an expression
...100)
t <- t/1000
plot(eval(h), type = 'l')
# however this yields an error
h <- h/sqrt(sum(h^2))
Error in h^2 : non-numeric argument to binary operator
what shall I do to get the matlab: h = h/norm(h) implemented in R?
thanks for a hint

..., or do h <- eval(h) beforehand.
