Structure in simulink and Embedded MATLAB Function
显示 更早的评论
Hi everyone.
I'm trying prove a example of Mathworks about structure in Simulink , You can find It in the help of Matlab "Example of Structures in an Embedded MATLAB Function Block".
I do this exercise how you can look at the picture bellow( click on link bellow)
In that case , it work , but when I change "a2" with a matrix for example [2 3;4 6] and I changed the code too, look at the picture (click on link bellow)
in that case it doesn't work , appears a error window :
I attached the files of program simulink and buses: https://sourceforge.net/projects/simustruct/files/SimulnkStructure.rar/download
I hope You can help me

Are you working with the demo model named 'emldemo_bus_struct'? If yes, what version are you using? I'm asking because in R2011b, it appears that the model already uses a 2x2 matrix for that last element of the bus. In any case, it seems like you may not have updated the Simulink.Bus in the base workspace to also use a 2x2 matrix. You need to look at the "Output Data Type" setting in the dialog of the Bus Selector that the bottom two Constant blocks are connected to. You will see a Simulink.Bus object with the same object. If it's called SubBus:
>> busEls = SubBus.Elements;
>> busEls(2)
ans =
Simulink.BusElement
Name: 'a2'
Complexity: 'real'
Dimensions: [2 2]
DataType: 'int8'
Min: []
Max: []
DimensionsMode: 'Fixed'
SamplingMode: 'Sample based'
SampleTime: -1
See that the "Dimensions" field says "[2 2]".
