Assignment through repeated indexing on LHS |

(Couldn't find it in the manual or on the web)
I wonder if the following is a legal construct:
cell_array(:, 3:5)(index-vector) = some_value
or with a real example (invoking the testc cell array in attached testc.mat
<http://octave.1599824.n4.nabble.com/file/t131602/testc.mat> ) I tried:
load testc.mat
idx = find (cellfun (@isempty, testc(:, 3:8)));
testc(:, 3:8)(idx) = NaN
...yielding the following somewhat incomprehensible (to me) error message:
error: () must be followed by . or close the index chain
Am I correct to conclude that repeated indexing on the LHS of an expression
is illegal, or at least unsupported?
In that case I think the error message could be more clear, like explicitly
mentioning that repeated indexing on LHS is not permitted.
Typing:
testc(:, 3:8)(idx)
works fine of course as it is essentially a RHS expression.
Thanks,
Philip
