Quasi-Newton Methods (Mathematica Tutorial)

There are many variants of quasi-Newton methods. In all of them, the idea is to base the matrix B_k in the quadratic model on an approximation of the Hessian matrix built up ...

Working with Operators (Mathematica Tutorial)

You can think of an expression like f[x] as being formed by applying an operator f to the expression x. You can think of an expression like f[g[x]] as the result of composing ...

JavaBlock (JLink Symbol)

JavaBlock[expr] causes all new Java objects returned to Mathematica during the evaluation of expr to be released when expr finishes. It is an error to refer to such an object ...

ReturnAsJavaObject (JLink Symbol)

ReturnAsJavaObject[expr] causes a Java method call or field access during the evaluation of expr to return its result as an object reference (a JavaObject expression), not a ...

NETBlock (NETLink Symbol)

NETBlock[expr] causes all new .NET objects returned to Mathematica during the evaluation of expr to be released when expr finishes.

ReturnAsNETObject (NETLink Symbol)

ReturnAsNETObject[expr] causes a .NET call during the evaluation of expr to return its result as an object reference (i.e., a NETObject expression), not a value.
