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:
a = jarray("java.lang.Double",3,1)
a(1) = [1 2 3]
a(2) = [4 5]
a(3) = 6
Next, I attempted to create a primitive double array instead:
b = jarray("double",3,1)
b(1) = [1 2 3]
b(2) = [4 5]
b(3) = 6
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:
!--error 999
%s_i__EObj: An error occurred: Exception when calling Java method :

It looks like it considers scalar values as Double type and not the
primitive double. Is there a way to overcome this? Thanks!
Hi,
It is a bug so please report it at bugzilla.scilab.org.
A temporary workaround:
c=jarray("double",1);c(1)=6;
b = jarray("double",3,1)
b(3)=c
Best regards
