Remarks

Error code

The error codes that can occur on a matrix are as follows:
  • 8: Insufficient memory.
  • 9: The requested position is outside the matrix.
  • 10: The name of the matrix is invalid.
  • 11: The matrices have different dimensions.
  • 12: The determinant is null. Unable to calculate the inverse of the matrix.
Caution: A WLanguage error is triggered by the errors 9, 10 and 11. The application stops.

Matrix existence

The matrix existence is not checked. To check the matrix existence, use MatExist.
