 Polly automatically detects and optimizes generalized matrix multiplication,
 the computation C |larr| α ⊗ C ⊕ β ⊗ A ⊗ B, where A, B, and C are three appropriately sized matrices,
-⊕ and ⊗ operations are originating from the corresponding matrix semiring, and α and β are
+⊕ and ⊗ operations are originating from the corresponding matrix semiring, and α and β are
 constants, and beta is not equal to zero. It allows to obtain the highly optimized form structured
 similar to the expert implementation of GEMM that can be found in GotoBLAS and its successors. The
 performance evaluation of GEMM is shown in the following figure.
