FRED如何调用Matlab

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。 < >UPD02  
3@5=+z~CW  
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: %uv?we7  
enableservice('AutomationServer', true) l5l>d62  
enableservice('AutomationServer') w9 w%&{j  
Fnk_\d6Ma  
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。 n|GaV  
hOhS)  
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: .0R v(Y  
1. 在FRED脚本编辑界面找到参考. _gKe%J&  
2. 找到Matlab Automation Server Type Library XeBP`\>Ve  
3. 将名字改为MLAPP u?s VcD[  
r`c_e)STO  
5[j`6l  
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。 - 0?^#G}3}

现在将脚本代码公布如下,此脚本执行如下几个步骤: ~=R SKyzt  
1. 创建Matlab服务器。 eNiaM6(J  
2. 移动探测面对于前一聚焦面的位置。 1-.~7yC  
3. 在探测面追迹光线 oK{ V7  
4. 在探测面计算照度 PRNoqi3sY  
5. 使用PutWorkspaceData发送照度数据到Matlab k6=nO?$  
6. 使用PutFullMatrix发送标量场数据到Matlab中 vkLC-Mzm<  
7. 用Matlab画出照度数据 VLBE'3Qg 1  
8. 在Matlab计算照度平均值 r>GZ58i  
9. 返回数据到FRED中 xkOpa,=FI
