Undocumented Secrets of MATLAB-Java Programming

from within Java

directly invoke MATLAB’s exit command as opposed to eval(‘exit’), since all other proxy

methods block (pause) until completion, but in the case of exiting MATLAB no signal will ever

be sent by MATLAB to indicate that it has closed.

9.4.3 Parsing MATLAB’s Return Values

Our eval commands are being sent using RemoteMatlabProxy’s returningEval(String

command, int returnCount) method, whose return type is Object, because MATLAB can

return multiple return types. For example, the expression “sqrt(5)” will return an array of dou-

bles, “pwd” will return a java.lang.String, and “whos” will return a complicated array of

arrays with a variety of base types and Objects.

This behavior may be different on dif ...
