Matrix square-root may or may not be something you want to solve symbolically. SymPy will certainly let you represent it symbolically, but it has proven unable to compute it numerically.. Hi there! This page is only going to make sense when you know a little about Systems of Linear Equations and Matrices, so please go and learn about those if you don't know them already!However, already 3 by 3 case is problematic, and 1000 by 1000 is utterly hopeless. One doesn't simply solve a system of 500,000 nonlinear equations by throwing it at SymPy. import sympy as sym X = sym.Matrix(sym.MatrixSymbol('X', 2, 2)) covar = sym.Matrix([[2, 1], [1, 3]]) sym.solve([X**2 - covar*X - sym.eye(2), X-X.T], X) Notice that multiplication of SymPy matrices is just *. The first equation is what you wrote, the second requires X to be symmetric (X.T is the transpose of X). X^2 - CX - I = 0 -> X^2 + 2EX - I = 0 // sub C = -2E -> X^2 + 2EX + E^2 - I = E^2 //add E^2 to both sides (i.e., complete the square) -> (X + E)^2 = E^2 + I //simplify and add I to both sides -> X+E = +/-(E^2 + I)^(1/2) //take square root (now we may have more than one answer) -> X = -E +/- (E^2 + I)^(1/2) //subtract E from both sides Matrix square-root may or may not be something you want to solve symbolically. SymPy will certainly let you represent it symbolically, but it has proven unable to compute it numerically, thus far in my attempts (in Python3 on MinGW64).
Solving Simultaneous Linear Equations. See also: matrix, Gauss-Jordan elimination, Geometric Linear Transformation. Simultaneous Linear Equation Solver. Choose the size of the system Thus the square-root via diagonalization of (4) above could be used. And the square-root of a diagonal matrix is computed by taking the square-root of the elements on the diagonal. Here you may run into another issue, that if these elements are negative, your answer will be complex. There are also potentially multiple answers for each square-root, potentially giving you a few answers to consider. This is most likely why SymPy fails to give a numerical answer.It didn't look as neat as the previous solution, but it does show us that there is more than one way to set up and solve matrix equations. Just be careful about the rows and columns!More general systems involving nonlinear functions are possible as well. These possess more complicated solution sets involving one, zero, infinite or any number of solutions, but work similarly to linear systems in that their solutions are the points satisfying all equations involved. Going further, more general systems of constraints are possible, such as ones that involve inequalities or have requirements that certain variables be integers.
2 Your code isn't right. NumPy is for numerical computation, it is not going to create a SymPy object representing the left hand side of your equation. And it's not going to help you obtain an analytic solution. Here is an example of solving a matricial system with SymPy; it is 2 by 2 rather than 1000 by 1000. And because of the way that matrices are multiplied we need to set up the matrices differently now. The rows and columns have to be switched over ("transposed"):The solutions to systems of equations are the variable mappings such that all component equations are satisfied—in other words, the locations at which all of these equations intersect. To solve a system is to find all such common solutions or points of intersection. To solve your equation using the Equation Solver, type in your equation like x+4=5. The solver will then show you the steps to help you learn how to solve it on your own Sal solves a linear system with 3 equations and 4 variables by representing it with an augmented matrix and bringing the matrix to reduced row-echelon form
This calculator solves system of three equations with three unknowns (3x3 system). The calculator will use the Gaussian elimination or Cramer's rule to generate a step by step explanation Working up from C we ask, is E^2+I diagonalizable (so as to have an easy explicit formula for matrix square-root)? C is symmetric, and E = -(1/2)C; the scalar multiply doesn't change the symmetry of C since it affects every cell; hence E is symmetric. E^2 = (E * E) commutes, so E^2 is symmetric. Finally, I is symmetric, so (E^2 + I) is symmetric.
You could try SciPy's multivariable solvers to obtain some numerical solutions, but it's going to be just that, one numerical solutions of many. The right approach to matricial equations like X**2 - C*X - I = 0 is not to throw them at a computer; it is to do math. Here you can solve systems of simultaneous linear equations using Inverse Matrix Method Calculator with complex numbers online for free. All the auxiliary methods used in calculation can be calculated.. It means that we can find the values of x, y and z (the X matrix) by multiplying the inverse of the A matrix by the B matrix.Your matrix C is symmetric, so we can check whether the term under the square-root (i.e., power of 1/2) has an explicit computation formula. A few preliminary facts:

Systems of linear equations are a common and applicable subset of systems of equations. In the case of two variables, these systems can be thought of as lines drawn in two-dimensional space. If all lines converge to a common point, the system is said to be consistent and has a solution at this point of intersection. The system is said to be inconsistent otherwise, having no solutions. Systems of linear equations involving more than two variables work similarly, having either one solution, no solutions or infinite solutions (the latter in the case that all component equations are equivalent).Enter your queries using plain English. To avoid ambiguous queries, make sure to use parentheses where necessary. Here are some examples illustrating how to ask about solving systems of equations.
