MatError (Function) In french: MatErreur // 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 Name of the matrix used, defined with MatCreate. Remarks 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.
