When trying to use any example from examples directory I get following error:
sedumi(At,b,c,K)
error: whichcpx: Assertion failed: nlhs <= 1, at line 154 of file "whichcpx.c".
whichcpx generates 1 output argument.

I think that building did not pass correctly.

For a possible explanation and fix see https://savannah.gnu.org/bugs/index.php?50050 . It does not seem to be an issue of SeDuMi. I faced the same issue and now all examples work for me again.

mexproto.h (mxAssert, mxAssertS): ensure operator precedence (bug #50…
1bb5e45 
…050)

* mexproto.h (mxAssert, mxAssertS): add parenthesis to the macro parameter expr.
This avoids errors due to the operator precedence of the negation.  See bug was
first observed at: sqlp/sedumi#24.

Upstream Octave bug was fixed in 2017 and should no longer be a problem with newer versions of Octave.
