Mathematica contains some powerful primitives for making structural changes to expressions. You can use these primitives both to implement mathematical properties such as ...

The following techniques are useful for debugging problems with client connections to the license server. MathLM will not start if it cannot find the password file. In that ...

Even with "Newton methods" where the local model is based on the actual Hessian, unless you are close to a root or minimum, the model step may not bring you any closer to the ...

"Gauss–Newton" and "conjugate gradient" methods use derivatives. When Mathematica cannot compute symbolic derivatives, finite differences will be used. Computing derivatives ...

Module and With allow you to give a specific list of symbols whose names you want to treat as local. In some situations, however, you want to automatically treat certain ...

Most of the documentation provided for Mathematica is concerned with explaining what Mathematica does, not how it does it. But the purpose of this is to say at least a little ...

CUDAImageMultiply[img, x] multiplies an amount x to each channel value in img.CUDAImageMultiply[mem, x] multiplies an amount x to each channel value in ...

SQLColumn[...] represents a column in an SQL table.

The raw SQL command CREATE TABLE creates tables in a database. An alternative is to use the Mathematica command SQLCreateTable, described in "Creating Tables". If you find ...
