During the 4 hour work on converting the statistics stuff
today I have collected the most urgent questions/suggestions
for matlab compatibility.
=== 1 ===
The notation y = x(:) does not work. This is
very much cleaner than y = reshape(x,prod(size(x)),1).
And A(find(A>0)) should give me a column vector.
Please copy the matlab conventions since they are
very effective. Also x(:,ones(m,1)) for a column vector
x is very useful.
=== 2 ===
y(:) = x does not work either. y = reshape(x,size(y,1),size(y,2))
is not more readable or writable. And while we're at it:
y(find(y<0)) = 0 with scalar right hand side will work
in matlab 5.0 says mathworks, this is a good thing too.
=== 3 ===
Skip the "warning: empty matrix found in matrix list"-
error message. I know what I'm doing.
=== 4 ===
Skip the read-only property of I and J. I want to
use them as I want too. Besides I already have written
matlab-programs with lots of I and J.
=== 5 ===
The old style rand crashes many programs. rand([3 4])
means a 3 x 4 - matrix im matlab 4.x, not a 1 x 2 one.
This will be changed in octave I think somebody said?
