 WINDEV      WEBDEV    WINDEV Mobile       Others MatDeterminant (Function) In french: MatDéterminant Calculates the determinant of a square matrix (the number of rows is equal to the number of columns).Example // Calculate the determinant of a matrixResDeterminant = MatDéterminant("MyMatrix") Syntax = MatDeterminant() : RealDeterminant of matrix. The determinant of matrix is null if this value is equal to 0. : Character stringName of the matrix to be used, defined with MatCreate. Remarks Matrix existenceThe matrix existence is not checked. To check the matrix existence, use MatExist.Managing errorsCaution: MatDeterminant returns no error code. To find out whether errors have been generated when calculating the determinant, use MatError. To get more details on the error, use ErrorInfo with the errMessage constant.Business / UI classification: Neutral codeComponent: wd280mat.dll Minimum version required Version 9 This page is also available for…
