    简介:FRED作为COM组件可以实现与Excel、VB、Matlab等调用来完成庞大的计算任务或画图,本文的目的是通过运行一个案例来实现与Matlab的相互调用,在此我们需要借助脚本来完成,此脚本为视为通用型脚本。 kzG m D i  
    )z/+!y  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: [V~(7U  
    enableservice('AutomationServer', true) TC80nP   
        enableservice('AutomationServer') )\C:|  
    V]cD^Fqp  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 $9DV }

    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: \`\& G-\  
    1. 在FRED脚本编辑界面找到参考. CA)DQYp{  
    2. 找到Matlab Automation Server Type Library `H6-g=C  
        3. 将名字改为MLAPP `Ym7XF&

    在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix,PutWorkspaceData适用于存储一般的数据在工作区,并赋予其为变量,PutFullMatrix试用于复数数据。 lC Bb0k2

    4. 在探测面计算照度 ct+ ;W  
    5. 使用PutWorkspaceData发送照度数据到Matlab nFU'DZ  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 JsohhkJNGi  
    7. 用Matlab画出照度数据 3-z; pk
