Hi,
I wrote a little function to generate maximum length pseudo random
sequences, the function returns a vector. I am doing some matrix
multiplication with this vector and notice that in octave 2.1.50 the vector
is treated as row vector, whereas in 2.1.53 it is treated as a column
vector. Simple example:
octave:1> a(1)=1
a = 1
octave:2> a(2)=2
a =
1
2
octave:3> version
ans = 2.1.50
octave:4> [nr,nc]=size(a)
nr = 2
nc = 1
octave:1> a(1)=1
a = 1
octave:2> a(2)=2
a =
1 2
octave:3> version
ans = 2.1.53
octave:4> [nr,nc]=size(a)
nr = 1
nc = 2
Is this expected behaviour and if so is it going to stay that way? A quick
search didn't show anything in the changelog, but maybe I was looking for
the wrong thing.
Thanks,
Christian
