In order to understant mxj's JitterAPI, i tried to adapt the Javascript particle systeme of the tutorial of Javascript in mxj.

Expr1.matrixcalc([vitP,tmp,accel,lth],vitP);

In JAVA, a such syntaxe is impossible according to the compiler.

I thought about converting into a Atom array but it stills not correct.

JS allow me to type this:
Expr1.matrixcalc([vitP,tmp,accel,lth],vitP);
Where :
  Expr1 is a JitterObject -> jit.expr
  vitP is a 3dim Matrix
  lth is a 1dim Matrix
  accel is a regular float

I'm not quite sure what you're trying to achieve, but the JitterObject API docs give details of the 

 method and its arguments. On the Mac the docs are here:

I already looked in the documentation, Let's take an example

Here is the only way to use the matrixcalc methode according to the documentation.

public boolean matrixcalc(java.lang.Object input,

In the jit.expr Max object (in the max envorinement), I can use several inlets that recieves many kind of values (int, float, Matrix...).

"matrix1 * a_float - an_int / sqrt(of something)" -> @expr "in[0]*in[1]-in[2]/sqrt(in[3])"

var myexpr = new JitterObject("jit.expr");

myexpr.expr = "in[0]*in[1]-in[2]/sqrt(in[3])";

Expr.matrixcalc([myMatrix,myFloat,myInt,myAlmostAnything],myResult);

But in JAVA(not JS) making a suck array of different type doesn't seem to be accepted.

I tried to use casts but it stills don't work.

So question is : How to perform in mxj a such matrix operation ?

public boolean matrixcalc(java.lang.Object input,
                          java.lang.Object output)
so one input and one output.

for exemple :
"matrix1 * a_float - an_int / sqrt(of something)" ->  @expr "in[0]*in[1]-in[2]/sqrt(in[3])"
which returns a matrix.

var myexpr = new JitterObject("jit.expr");
myexpr.expr = "in[0]*in[1]-in[2]/sqrt(in[3])";

and perform this way
Expr.matrixcalc([myMatrix,myFloat,myInt,myAlmostAnything],myResult);

This works in the JS Jitter tutorial(46)
