There is no MATLAB function that examines every level of a structure of structures, or nested structure, to determine if a field exists. The 'isfield' function examines only the top level of a nested structure. To determine if a field exists at any other level, y...
I have a structure with quite some fields and I want to check, if any of the fields are empty. Is there a way to do this without checking for each field individually? Currently I have an if statement with many ORs to do this: ThemeCopy if isempty(structure.field1) || isempty(s...
% boolean: true if the field exists at the specified location, false if not (boolean) existField Examples: % Create a sample structure struct.a(1).b=1; struct.b(1,2).c=1; struct.d(2).e=1; fldName='b';% Dynamic field name ...

由于gui_Create为真,这里if语句的判断结果肯定为假。然后程序首先判断了窗口的Singleton性质和可见性。由于这里程序太长,下面再分块分析。 代码语言:javascript 复制 %Do feval on layout codeinm-fileifit exists gui_Exported=~isempty(gui_State.gui_LayoutFcn);%thisapplication data is used to indicate the ru...
This structure does not have a field 'rbm'; new fields cannot be added when structure has been read or used. #MATLAB Coder function dbn = randDBN( dims, type ) #codegen %coder.extrinsic('cell'); % dbn.rbm = cell( numel(dims)-1, 1 ); %...
Where the atom variable becomes an indexed Matlab struct variable - containing all your molecules attributes like atom names, coordinates and more. Note that you also get the box dimension variable Box_dim holding the box size if such exists. ...
