i tried to use a constant for function minimization. i coded:
a=2
fun1=inline('(a*x-1)^2')
fmins(fun1,0)
octave gives me
a = 2
fun1 =
f(a, x) = (a*x-1)^2
error: `x' undefined near line 2 column 12
error: evaluating binary operator `*' near line 2, column 11
error: evaluating binary operator `-' near line 2, column 13
error: evaluating binary operator `^' near line 2, column 16
error: called from `?unknown?'
error: evaluating binary operator `*' near line 63, column 12
error: evaluating assignment expression near line 63, column 6

error: called from `fmins' in file
`/usr/share/octave/site/m/octave-forge/optim/fmins.m'
error: near line 3 of file `/usr/share/octave/site/m/minimization.m'
how can i define function with a=2?
