MATLAB:: -nojvm 启动选项下不再支持此功能

Question

我在终端中运行 Matlab 代码，因为稍后我需要在 php 中调用它。但是我得到了这些错误：

jalal@klein:~/Desktop/v1.2$ matlab -nojvm < matlab.m

错误：

L2 norm on unsampled vertices: 0.096158

你能指导我如何解决这个问题，或者我还能如何从 PhP 运行 Matlab 代码？目前我可以从php运行ls -ltr之类的命令并在网页上查看结果！

Answer 1

根据您收到的错误消息，不再支持使用-nojvm 处理图形。你应该改用-nodesktop。

在您的环境中，应该是：

jalal@klein:~/Desktop/v1.2$ matlab -nodesktop < matlab.m

http://www.mathworks.com/help/matlab/release-notes.html#btsurqv-6

以下是受影响功能的摘要：

• 创建图形和执行绘图任务，例如使用绘图、轴、getframe 和 gcf 函数。
• 打印图形并使用相关功能，例如 print、hgexport 和 saveas。
• 使用 GUI 构建函数（例如 warndlg）在 MATLAB 中创建 GUI。 使用 Simulink 示波器并打印 Simulink 模型。

Answer 2

您已禁用最新版本的 MATLAB 中图形所需的 JVM。如果您需要图形但不需要 IDE，可以使用-nodesktop -nosplash 启动 MATLAB。 -nosplash 选项确保不显示 MATLAB 启动屏幕。

matlab -nodesktop -nosplash
