What is LU Decomposition Calculator with Steps?
LU matrix decomposition calculator is an online matrix calculator that is used to factorize a square of any order into two distinct triangular matrices. These triangle matrices form individually one lower triangle matrix (L) and one upper triangle matrix (U).
This lu decomposition method calculator offered by matrix solver calculator uses the LU decomposition method in order to convert a square matrix to upper and lower triangle matrices. The decomposition formula used by this lu calculator states,
A = PLU

Remembering the formula above which is A = PLU.. So the square matrix in the formula is given as A, while the P represents the Permutation Matrix. The LU decomposition also known as LU factorization is considered as the matrix form Gaussian Elimination. And we know that this can be messy, and to solve this mess we introduce you the lu matrix calculator online for free.
This lu matrix decomposition calculator is an effective tool for linear algebraic problem-solving. As linear algebraic operations and numerical analysis is involved in the LU decomposition performed on the square matrix to factorize into triangle matrices.

How to solve LU Decomposition?
The LU decomposition or factorization involves converting the square matrix into two triangular matrices. The formula is A = PLU. Where A is the square matrix and P is the permutation of matrix.The manuall way can be lengthy but you can solve easily through lu factorization calculator online.
What is P in LU decomposition?
P is the Permutation matrix. This permutation matrix is calculated in the case of partial pivoting. As sometimes solving linear equations using lu factorization calculator, it also gives another matrix, which is Permutation matrix in the results.
Does LU Decomposition always exist?
LU Decomposition of any linear system is always exists as it helps to find out the determinant of a matrix. If the determinant of a matrix is not 0, then pure LU decomposition exists only if principal minors are not 0.
Thus we can easily check decomposition exists or not by using lu decomposition online calculator within a second.
