2.1.41 PutMatrix


Put two dimensional data into a specified Origin matrix.


VB: Function PutMatrix(Name As ByVal String, data As ByVal Object ) As Boolean
C++: bool PutMatrix(LPCSTR Name, _variant_t data )
C#: bool PutMatrix(string Name, var data )


The range string of the Origin worksheet to be found. The range string contains the book name between square brackets followed by the sheet name:
The following special notations are supported. When any of the three parts are not specified then the active is used:
  1. "" (empty string) -- get the active object from the active sheet from the active book
  2. "[MBook1]" or "MBook1" -- get the active object from the active sheet from the named book
  3. "[MBook1]MSheet1" or "[MBook1]MSheet1!" -- get the active object from the named sheet from the named book
  4. "MSheet!" -- get the active object from the named sheet from the active book
  5. "MSheet!0" -- get the specified object from the named sheet from the active book
Two dimensional safearray containing the data that will be put into the Origin matrix.


The PutMatrix method returns true if successful else false.
