There are many ways to decompose a matrix A into matrices whose product is also A.  The following functions are supported by MathStudio,

• LUDecomposition(A) is a function that computes the LU decomposition of a matrix.
• Cholesky(A) is a purely numerical function that computes the Cholesky decomposition of a symmetric positive-definite matrix (uses the TNT library).
• QR(A) is a purely numerical function that computes the QR decomposition of a matrix (uses the TNT library).
• SVD(A) is a purely numerical function that computes the Singular Value decomposition of a matrix (uses the TNT library).
