Thanks, that was enought of a hint to get me started. Could anyone
check that the following is correct?
Very cool! I will check soon if nobody else comes first.
...
mwrite(xy, "(a)dotdir/xy.mat")
OT: I know about the return value of mwrite(), but this "feels" more
like a command than a function. Or to put it differently: if I
understand correctly you recently introduced more sophisticated error
handling ($error and stuff). I wonder whether a mish-mash is being born
right now, sometimes getting error codes from function return values,
and sometimes from accessor variables?
colnames(h, "coherence")
OT again: another function used like a command -- how many are there?
(And I thought I knew gretl script by now...)
gnuplot 1 --time --with-lines --matrix=h --output=display
final OT comment: see how great it is to be able to plot matrix columns
;-) I also find the new (?) display option very useful.
thanks,
