Matlab MCR 缺少内部 class

Question

在安装并配置了 MCR 8.3 的 Ubuntu 机器上执行 Matlab，出现以下错误：

The class "internal.optim" is undefined.
Perhaps Java is not running.

Error in internal.optim.presolve (line 211)
Error in ipqpcommon (line 30)
Error in quadprog (line 353)
Error in mv_low_level_solver_quadprog (line 72)
Error in mv_optim_min_risk (line 47)
Error in Portfolio/estimateFrontierLimits (line 79)
Error in portafoglio (line 63)

显然 Java 是运行，如果我尝试执行其他 Matlab 函数，我没有问题。可能是什么问题？

更新如果我使用相同的 MCR 在 Windows 上执行相同的代码...它有效...

Answer 1

我很确定它是在 Windows 上编译的。从 v83 开始，包含转换后的库的生成的 jar 还包含一个 .ctf 文件，它是一个包含 Windows DLL 的类似 zip 的包。要解决这个问题，你应该重新编译你的 jar（我知道这听起来很奇怪，因为 java 座右铭到处都是写一次运行但是......这不是 java 问题） linux 在 64 位。

干杯， VD
