  • is the array of numeric elements.
    • MINVERSE(), returns the matrix inverse of an array.


  • This function gives the inverse matrix for the given matrix.
  • We have to find a inverse of a matrix then it should satisfy the following conditions
  • 1.A matrix must be a square matrix.
  • 2.It's determinant not equal to 0.
  • Let be the 2x2 matrix with the elements


  • Then the inverse of matrix is denoted by .
  • Now let be the matrix is of order .
  • Then the inverse of is
  • Where is the adjoint of .
  • Adjoint is the matrix formed by taking the Transpose of the Co-factor matrix of the original matrix.
  • Also , where is the identity matrix.
  • Non-square matrices do not have inverses.
  • Not all square matrices have inverses.
  • A square matrix which has an inverse is called invertible or non-singular, and a square matrix without an inverse is called non-invertible or singular.
  • This function will return the result as error when
1. Any one of the cell is non-numeric or any cell is empty or contain text
2. Suppose number of rows not equal to number of columns


  • The syntax is to calculate the inverse of the matrix in ZOS is .
    • is the array of numeric elements.
  • For e.g.,minverse([[10,12],[11,14]])


, because its determinant value is 0.
