Octave basics: How to assign variables from a vector

Question

Maybe I'm spoiled by Python, but does Octave allows one to assign the values of variables directly from a vector? That is, doing something like

a,b,c=[5,6,7]

will result with a=5, b=6, c=7. I have tried many combinations of writing the expression above, but no luck yet ...

This can be done by constructing a cell array with "{...}" and converting this to a comma separated list via "{:}":

[a b c] = {5 6 7}{:}
a =  5
b =  6
c =  7

spiffy, just to complete the picture, here's how to do that starting from a vector: mat2cell([5 6 7], 1, [1, 1, 1]){:} – r0u1i Jul 05 '12 at 09:41
is it really the best way to do this in octave ?? – nicolas Apr 28 '13 at 15:10

This seems to work when you actually have a vector to deal with:

v = [5, 6, 7];
[a, b, c] = num2cell(v){:}

deal() is meant for this task, for separate input values:

>> [a,b,c] = deal(5,6,7)
a = 5
b = 6
c = 7
