function sum does not work: {sum(myArray[1:i]) for i in 1:dimensions}

function sum does not work: {sum(myArray[1:i]) for i in 1:dimensions}

Jan-06-12 22:33:32

hello,

just realized that the following statement does not work, although it should:

Code:




model OMtest



parameter Integer dimensions = 5;



parameter Real myArray[dimensions] = {1,2,3,4,5};



parameter Real mySumArray[dimensions] = {sum(myArray[1:i]) for i in 1:dimensions};



end OMtest;

following error:
[SimCodeC.tpl:5647:11-5647:11:writable] Error: Template error: ASUB_EASY_CASE 1:1
[SimCodeC.tpl:5647:11-5647:11:writable] Error: Template error: ASUB_EASY_CASE 1:2
[SimCodeC.tpl:5647:11-5647:11:writable] Error: Template error: ASUB_EASY_CASE 1:3
[SimCodeC.tpl:5647:11-5647:11:writable] Error: Template error: ASUB_EASY_CASE 1:4

where is actually the official OM bug list? I mean it doesnt make sense if I remind you of bugs that are already known and somewhere reported for being fixed... current/smile .
and who is allowed to modify this list?
thanks

Fun bug current/smile
The link to the issue tracker is below, and I don't think I've seen this issue with sum-reductions before:

Anyone registered to the codebeamer should be able to post bug reports.

hello,
just updated to revision 10901 and tried my test model from above. I am afraid, it doesnt work, although it should since r10870?

following output:

OMtest.c: In function ‘eqFunction_0’:
OMtest.c:168:63: error: expected expression before ‘:’ token
OMtest.c: In function ‘eqFunction_1’:
OMtest.c:177:63: error: expected expression before ‘:’ token
OMtest.c: In function ‘eqFunction_2’:
OMtest.c:186:63: error: expected expression before ‘:’ token
OMtest.c: In function ‘eqFunction_3’:
OMtest.c:195:63: error: expected expression before ‘:’ token
OMtest.c: In function ‘eqFunction_4’:
OMtest.c:204:63: error: expected expression before ‘:’ token

could you paste lines 168-177 of the file for me? it seems to be a colon instead of semicolon output from some place but it should help if i know what code was generated

here lines 165-181

Code:




void eqFunction_0(_X_DATA *data, _OMC_SEED_HACK) {

  real_array tmp0;

  /*#modelicaLine [/home/fzaversky/workspace/OM/OMtest.mo:12:1-12:82]*/

  real_array_create(&tmp0, ((modelica_real*)&($PmyArray)), 1, :);

  $PmySumArray$lB1$rB = sum_real_array(&tmp0); 

  /*#endModelicaLine*/

}





void eqFunction_1(_X_DATA *data, _OMC_SEED_HACK) {

  real_array tmp1;

  /*#modelicaLine [/home/fzaversky/workspace/OM/OMtest.mo:12:1-12:82]*/

  real_array_create(&tmp1, ((modelica_real*)&($PmyArray)), 1, :);

  $PmySumArray$lB2$rB = sum_real_array(&tmp1); 

  /*#endModelicaLine*/

}
