In linear algebra, a standard symplectic basis is a basis ${\displaystyle {\mathbf {e} }_{i},{\mathbf {f} }_{i}}$ of a symplectic vector space, which is a vector space with a nondegenerate alternating bilinear form ${\displaystyle \omega }$, such that ${\displaystyle \omega ({\mathbf {e} }_{i},{\mathbf {e} }_{j})=0=\omega ({\mathbf {f} }_{i},{\mathbf {f} }_{j}),\omega ({\mathbf {e} }_{i},{\mathbf {f} }_{j})=\delta _{ij}}$. A symplectic basis of a symplectic vector space always exists; it can be constructed by a procedure similar to the Gram–Schmidt process. The existence of the basis implies in particular that the dimension of a symplectic vector space is even if it is finite.
