ECOS is written in low footprint, single-threaded, library-free ANSI-C and so runs on most embedded platforms. The main interior-point algorithm is a standard primal …
WebThe function ECOS_csolve is a wrapper around the ecos csolve C function. Conic constraints are specified using the \(G\) and \(h\) parameters and can be NULL and zero length vector respectively indicating an absence of conic constraints. Similarly, equality constraints are specified via \(A\) and \(b\) parameters with NULL and empty vector values representing …
