allocate-columns clj

(allocate-columns exprs)

Given a seq of expressions (sym -> coefficient maps), choose a unique index for each symbol.

coefficient-vector clj

(coefficient-vector expr column-allocation)

Turn an expression into a dense coefficient vector suitable for use with commons math, using the columns given in column-allocation.

make-constraint clj

(make-constraint lhs-coefficients relationship rhs-constant)

make-solution-map clj

(make-solution-map solution-vector column-allocation)

Turn a vector of solutions into a map, using the given column allocation

minimize clj

(minimize objective-expr constraints)

objective clj

(objective coefficients constant-term)

relationship-kw clj

solve clj

(solve objective constraints)

to-double-array clj

(to-double-array vec-or-map)

Convert a sparse vector (map of index to value) into a double array, with unfilled values set to zero. Regular vectors are converted directly.
