Using the "display()" command from a "Matlab Function Block" in simulink?
显示 更早的评论
i am trying to use the "display()" command in simulink by simply creating a "Matlab function block" and just writing the display command in it.
i get the following error :
"Undefined function or variable 'display'.
Function 'Bit Generation/MATLAB Function' (#182.47.57), line 3, column 1: "display(u)" "
i understand that not all matlab functions can be called from the Matlab function block. kindly tell me how to do what i am trying to do regards khurram

Use disp() instead.

Are you using an older version? disp() is supported in 2013b for sure.
On 2010a, I had to declare it extrinsic:
eml.extrinsic('disp')

It depends on when you want the code to run and how you plan to trigger it.
Go to "File->Model Properties" and select Callbacks and you will see different model actions that can trigger code to run. For example, put m-code in the "StartFcn" and it will run once at the start.
You can also try using the Interpreted MATLAB Function block, or just the plain Fcn block.
There are other ways to trigger by setting up events and listeners, but they are significantly more effort.
