<div dir="ltr">I was attempting to create a jagged array in
Scilab to be sent to a Java instance. At first, I created a
Double class array and had no problems:<br>
a = jarray("java.lang.Double",3,1)<br>
a(1) = [1 2 3]<br>
a(2) = [4 5]<br>
a(3) = 6<br>
<br>
Next, I attempted to create a primitive double array instead:<br>
b = jarray("double",3,1)<br>
b(1) = [1 2 3]<br>
b(2) = [4 5]<br>
b(3) = 6<br>
I had no problem with the first few lines. The problem occured
at b(3) = 6 when I attempted to assign a single element value.
I got this error:<br>
!--error 999 <br>
%s_i__EObj: An error occurred: Exception when calling Java
method : Array [[D@dbe4e5 cannot contain object which is an
instance of class java.lang.Double<br>

org.scilab.modules.external_objects_java.ScilabJavaArray.set(Unknown
Source)<br>

org.scilab.modules.external_objects_java.ScilabJavaObject.insert(Unknown

org.scilab.modules.external_objects_java.ScilabJavaObject.insert(Unknown

<br>
It looks like it considers scalar values as Double type and
not the primitive double. Is there a way to overcome this?
Thanks!<br>

Hi,<br>
<br>
It is a bug so please report it at bugzilla.scilab.org.<br>
<br>
A temporary workaround:<br>
c=jarray("double",1);c(1)=6;<br>
b = jarray("double",3,1)<br>
b(3)=c<br>
<br>
Best regards<br>
<br>
