Stored procedures
Initializes all the elements found in a matrix of a given size. If the matrix is larger, only the specified elements will be filled.
For example:
  • Initialize all the matrix elements with the value 5. This matrix contains 2 rows and 3 columns:
    ResFill = MatFill("MyMatrix", 5, 2, 3)
  • Initialize the matrix elements from row 1 to row 2 and from column 1 to column 3 with the value 5. Only part of the matrix is initialized:
    ResFill = MatFill("MyMatrix", 5, 2, 3)
// Fill a matrix containing 2 rows and 3 columns with the number 5
ResFill = MatFill("MyMatrix", 5, 2, 3)
Syntax
<Result> = MatFill(<Matrix> , <Value> , <Number of rows> , <Number of columns>)
<Result>: Boolean
  • True if the fill operation was performed,
  • False otherwise. To get more details on the error, use ErrorInfo with the errMessage constant.
