How to pass inputs to simulink for nested structures with array of structures

Hello,

I need to test the simulink model in Matlab 2016b which is having the structure type as below. I have already created the bus in the simulink for that structure.

Now I need to know how to create the inputs and pass to simulink block ?

a = struct ('b',1,'c',2,'d',struct('f',{3,4,5},'g',{6,7,8},'h',{struct('i',{9,10,11},'j',{12,13,14}),struct('i',{15,16,17},'j',{18,19,20})}))

Hi

You should create structure as like below.

a = struct ('b',1,'c',2,'d',struct('f',{3,4,5},'g',{6,7,8},'h', ...

{struct('i',{9,10,11},'j',{12,13,14}),struct('i',{15,16,17},'j',{18,19,20}), ...

struct('i',{21,22,23},'j',{24,25,26})}));

if you want to acess "h" from the above structure. we have to use as like. "a.d(1).h". Because "h" has three rows. the output would be.

Hi Murugan,

I would like to know how to pass that structure as input to simulink ? Could you please help me on this.

Hi VenkataPhanindra Challa

We have to create a structure with time series and signals. Then only we can this structure as input to the "From Workspace" simulink block.

For ex1.

% create struct with time series.

A.time = 0:10;

A.time = A.time';

A.signals.values = 1:11;

A.signals.values = A.signals.values';

A.signals.dimenstions = 1;

For ex2.

We can use a "constant" block also from simulink.

% create struct with using parameter.

Input1 = Simulink.Parameter;

Input1.Value = 1;

Input1.DataType = 'uint8';

Input1.Min = 0;

Input1.Max = 250;

Input1.RTWInfo.StorageClass = 'Custom';

Input1.RTWInfo.CustomStorageClass = 'Define';

As per my understanding, we can't use a structure what you have given.

a = struct ('b',1,'c',2,'d',struct('f',{3,4,5},'g',{6,7,8},'h', ...

{struct('i',{9,10,11},'j',{12,13,14}),struct('i',{15,16,17},'j',{18,19,20}), ...

struct('i',{21,22,23},'j',{24,25,26})}));

If I am worng, Please correct me.

Thanks in Advance !!!
