Identifies the type of the last error caused by a Matxxx function (functions for matrix management).
// Identify the type of error
ResError = MatError("MyMatrix")
Syntax
<Result> = MatError(<Matrix>)
<Result>: Integer
  • 0 if no error occurred on the matrix,
  • an error code (value greater than 0) otherwise.
<Matrix>: Character string (with quotes)
Name of the matrix used, defined by MatCreate.
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.
