<pre>This bug is related to <a class="bz_bug_link
bz_status_NEW "
title="NEW - Matrix indexing is not coherent with MATLAB convention"
href="show_bug.cgi?id=14487">bug #14487</a>, which should be fixed in a near future. In that case, the non-regression test which has been written for this bug
(#11405) should be rewritten, as it only checks that an hypermatrix can be used as a subscript. The problem is that until <a class="bz_bug_link
bz_status_NEW "
title="NEW - Matrix indexing is not coherent with MATLAB convention"
href="show_bug.cgi?id=14487">bug #14487</a> is fixed, when x
is not a scalar nor a vector and A is an hypermatrix, x(A) is always returned as a column vector regardless of the dimensions of A, e.g.
--> x
x =
1. 2.
3. 4.
--> A=ones(2,2,2)
A =
(:,:,1)
1. 1.
1. 1.
(:,:,2)
1. 1.
1. 1.
--> x(A)
ans =

In the bug report, It was pointed out two problems: 1-it was impossible to use an hypermatrix subscript, 2-the expected behavior was the one of
Matlab, i.e. in that case the output should be an hypermatrix. Hence, if <a class="bz_bug_link
bz_status_NEW "
title="NEW - Matrix indexing is not coherent with MATLAB convention"
href="show_bug.cgi?id=14487">bug #14487</a> is fixed, then the non-regression test of <a class="bz_bug_link
bz_status_RESOLVED bz_closed"
title="RESOLVED FIXED - error using hypermatrix"
href="show_bug.cgi?id=11405">bug #11405</a> will be
modified in order to verify that hypermatrix subscripts are accepted and that the size of the output is also correct.</pre>
