Hi,
f = Compile[{n}, Block[{i = 0}, Do[g[i, j], {i, 0,
n}, {j, 0, i}]]]
compile fine, and evaluate fine, even when it is
nonsense to use a compiled function here.
Regards

| How is it possible to compile the following code
structures in Mathematica:
|
| Do|Table[exp[i,j,...],{i,0,n},{j,0,i},...],
|
| for example in
|
| In[..]:=f=Compile[{n},Do[g[i,j],{i,0,n},{j,0,i}]
| Out[..]:= CompiledFunction[...]
|
| ?
|
| It does not work, when you use the compiled
function, since the compiler
| expects a integer expression for i...
|
| Do[Do[Do ... does not work either!
|
| This is such a basic construct!
