具有单元格数组的Matlab动态字段名称结构 [英] Matlab dynamic fieldnames structure with cell arrays

问题描述

如何使用动态字段名访问以下结构路径:

How can i access the following structure path with dynamic fieldnames:

var = 'refxtree.CaseDefinition.FlowSheetObjects.MaterialStreamObjects{8}.MaterialStreamObjectParams.Pressure.Value.Text';

fields = textscan(var,'%s','Delimiter','.');

refxtree.(fields{:})不起作用，因为MaterialStreamObjects包含一个单元格数组，我要访问该单元格的第8个单元格，然后继续沿结构路径向下移动.

refxtree.(fields{:}) does not work because MaterialStreamObjects contains a cell array of which I want to access the 8th cell and then continue down the structure path.

最后，我要获取并设置字段值.

In the end I want to get and set the fieldvalues.

推荐答案

在这种情况下，仅使用EVAL会更容易:

In this case, it is easier to just use EVAL:

str = 'refxtree.CaseDefinition.FlowSheetObjects.MaterialStreamObjects{8}.MaterialStreamObjectParams.Pressure.Value.Text';

%# get
x = eval(str)

%# set
evalc([str ' = 99']);
