Syntax
<Result> = mlSetVariable(<Session identifier> , <Variable name> , <Value>)

  • True if the variable was modified,
  • False otherwise. The ErrorOccurred variable is set to True if an error occurs. To get the details of the error, use ErrorInfo with the errMessage constant.
<Session identifier>: Integer
Identifier of MATLAB session. This identifier is returned by the mlInitialize function.
<Variable name>: Character string (with quotes)
Name of the variable to write.
<Value>: Array of integers, reals, ...
