We demonstrate the operation of a parallel matrix–matrix multiplier that uses a photorefractive crystal in conjunction with an array of mutually incoherent laser sources. A complex set of gratings is written in parallel with the aid of the mutually incoherent laser source array whose spatial modulation is the desired matrix–matrix product.
