    Linear Dependence Data field contains the list of input numbers for the integer relation algorithm. 
  • To add, delete or edit items in the list click on the item using the mouse and then press Enter. 
  • The linear dependence algorithm accepts Maple expressions and real or complex floating point numbers. Complex numbers are given in the form a + b*I. 
  • Precision field is to set the accuracy of the integer relation algorithm.
    Check Precision field is to separately set the accuracy for checking the output of Lindep.

Evaluation Precision field allows to separately set the accuracy of the evaluation procedure.
Alpha  field contains the input for the Find polynomialbutton to compute the minimal polynomial of the given number. Both Maple expressions and floating point numbers are accepted as input.
Degree field is to set the the maximal degree of the minimal polynomial. Minpoly precision field is to set the accuracy of the minimal polynomial algorithm. Check precision field is to set  separately  the accuracy checking the output of the minimal polynomial algorithm.
