matrix-operations

implementation of some of the matrix operations and solving linear equations using crummer rule

instruction

call the methods in class main.java

matrix operation methods in class MyMatrix

  • transpose
  • scalarMultiply
  • sum (sumation of 2 matrices and return the sumed matrix)
  • multiply (multiplication of 2 matrices and return the multiplied matrix)
  • validForMultiplication (check if 2 matrices valid for multiplication)
  • isSymmetric
  • equals (check if the two matrices are equals)
  • identityMatrix (static method return identity matrix)
  • zeroMatrix (static method return zero matrix)
  • inverse (return the iverse of matrix)
  • determinant (static method return determinant of matrix)
  • display (display the matrix )

solving linear equation

make instances of class MyEquation as required for the number of equation the equation can be either in array format or in a string format as

ax+by+cz=t such as
0x+2Y+Z=8

then add the equations to systemOfEquation object with method insertNewEquation(MyEquation x) then call method solve in systemOfEquation to solve the system and return array with the solution
