Have you seen the Java Applet Matrix Calculator? I have made a new matrix calculator this time using double arrays in Java, which can now calculate n x n matrices, up to 50 x 50.

BUT I did check my answer, and an alert will display if there is an erroneous solution. They arise geometrically from having either two parallel planes (no solutions) or having two planes being the same (infinite solutions).Д«oth cases were not handled very well by my programming. There are sets of equations which have no solution, and also systems which have infinitely many solutions. Which leaves you with the solution in the augmented portion of the matrix.ДЄ couple of problems do arise in particular systems. (flipping row(i) with row(k))Д«y applying these operations, you can reduce the matrix down so you have 1вЂ™s along the diagonal and zeroвЂ™s elsewhere. Example (Click to view) x+y7 x+2y11 Try it now Enter your equations in the boxes above, and press Calculate Or click the example.

Replacing a Row(k) with where i, k are any row System of Equations Calculator What do you want to calculate Systems of Equations Calculator is a calculator that solves systems of equations step-by-step.

Multiplying any Row by a Non-Zero Constant.

This is manipulating the equations by one of the following operations:

The technique I used to solve the system of equations is called row reduction, or reduced row eschelon form. Now how was this all done so magically using Java Script? Which can be easily checked by entering each value into any of the equations. This would be entered into the matrix above as : 1 2 3 : 9 The above solves a system of 3 equations and 3 unknowns, for example : x + 2y + 3z = 9 See the Pen Solve a Linear System of Equations by Marcus Kazmierczak ( on CodePen.
