outerProduct not implemented

[Christian Schubert]

I wrote a simple model using the outerProduct function

model outerProductTest
 Real n[3] = {1,2,3};
 Real a[3,3];
equation
 a = outerProduct(n,n);
end outerProductTest;

Unfortunately, it does not flatten giving the following errormessages:

[ModelicaBuiltin.mo:780:3-790:22:writable] Error: The lhs (result) of the external function declaration has array type (Integer[size(v1, 1), size(v2, 1)]), but this is not allowed in the specification. You need to pass it as an input to the function (preferably also with a size()-expression to avoid out-of-bounds errors in the external call).

Fixed in r13932

Now the model survives the frontend, but compilation fails.

Another problem occurs when compiling the slightly more complicated model

model outerProductTest2
 Real n[3] = {1,2,3};
 Real b[3,3] = identity(3);
 Real a[3,3];
 Real phi = 0;
equation
 a = (outerProduct(n, n) + identity(3))*b;
end outerProductTest2;

Then we get an error from the frontend saying:

[outerProductTest.mo:7:2-7:42:writable] Error: Incompatible argument types to operation matrix multiplication in component <NO COMPONENT>, left type: Real[:, :], right type: Real[3, 3]
[outerProductTest.mo:7:2-7:42:writable] Error: Cannot resolve type of expression (outerProduct(n, n) + identity(3)) * b. The operands have types Real[:, :], Real[3, 3] in component <NO COMPONENT>.
Error: Error occurred while flattening model outerProductTest

r13955 fixed the issue with code generation. Will look at the last part.

[Martin Sjölund]

See if r13961 works, then add a testcase for it and close the bug.

[Martin Sjölund]

Or wait for the commit that fixes all the problems... *Sigh*

[Martin Sjölund]

Ok, r13983 should work for sure. Add a testcase if it does.

[Martin Sjölund]

Postponed until 1.9.1
