A form of [[Matrix Product]] / [[Composition]] that is a piecewise multiplication between two [[Matrix|Matrices]] of the same [[Dimension]]. $\huge \forall A,B\in M_{n\times m} : (A\odot B)_{ij} = A_{ij}B_{ij} $ The [[Hadamard Product]] is a useful concept when dealing with [[Vector|Vectors]] representing [[Color]]. The product shows up as well for image processing, such as computing [[Convolution|convolutions]] via [[Fourier Transform|fourier transforms]].
