MATLAB to Java with MATLAB compiler

Question

Iam新增MATLAB，並希望在Java中使用一些MATLAB腳本。 我試過this來自MATLAB的教程。 我的MATLAB的功能，我想在Java中使用：

function y = makesqr(x) 

    y = magic(x); 

此MATLAB腳本應該被打包成Java包。 但創建二進制文件失敗後出現錯誤。 另外我可能沒有完全理解它應該工作的方式。 我可以將MATLAB腳本編譯爲Java，並且Java包可以在Java代碼中運行？

蔭使用的是Windows 64位與Java版本

1.8.0_121-b13 

Matlab具有

1.7.0_60-b19

Answer 1

我的解決方案是使用Java JDK 7，而不是Java的8 Matlab的不支持Java 8

安裝Java JDK並設置JAVA_HOME路徑。 Here是一個很好的描述

Answer 2

爲了能夠使用MATLAB編譯器將MATLAB文件打包到Java庫中，必須安裝和配置MATLAB使用的相同版本的JDK。 Java版本是MATLAB安裝使用，可以通過運行以下命令MATLAB獲得：

version -java 

此外，JAVA_HOME環境變量必須正確設置。 Configure Your Java Environment頁面包含更多信息。
