Undefined function or method '...' for input arguments of type 'double'.
2,917 次查看（过去 30 天）
I'm getting the following error when I try to run some function m-files: ??? Undefined function or method '[name of function]' for input arguments of type 'double'.
I know this usually happens when the file isn't in the working directory, but that's not the case here.
When I was running these m-files in a different directory on my computer, it worked fine. I moved them to another directory on my laptop, and they're still fine, but I get this error on two of my desktops.

I am pretty sure that the reason why this problem happened is because of the license of the toolbox (package) in which this function belongs in. Write
and see what will be the result. If it returns path of the function and the comment
"Has no license available",
then the problem is related to the license. That means, license of the package is not set correctly. Mostly it happens if the package (toolbox) of this function is added later, i.e., after installation of the original `matlab`. Please check and solve the license issue, then it will work fine.
In my case, there was a function that is used in my code but it was not in the directory, so by changing the location of the sub function and copying in the active directory , the problem is solved now.

change the working directory to the folder where you have your code or add the path.
Go to the File and choose the Set Path
Please consider that you should be EXACTLY in the same directory; and not even in sub-directories within the right path.
I hope this solves the case. It worked for me.

Are you function names in mixed case, and your laptop runs Windows but your desktop runs Linux ?

I've encountered this error when attempting to call MEX functions that were built/compiled on machines running a different version of Windows.
e.g. I build a MEX file from source code on a 32 bit machine, transfer it somewhere down the road to a 64 bit machine, and then attempt to call the function.
Seems like this error often has little to do with the arg type being 'double.'

in case of the sin(a) just dont put the '', then it works fine, at least on winxp 32bit

For me,the reason why this error occured was because I used a method that actually did not belongs to the object I used to invoke.This means that I should first transform my object to another type of data,for me,I actually have to change the object belongs to vehicle class to mini class to specify its data type. OOP's philosophy is indeed very important for you to understand why it occured and solve the error.

I met the problem ??? Undefined function or method 'cdfcalc' for input arguments of type 'double'. Besides, when I use cmd "which cdfcalc", returned that no such a function found. I wonder if I missed to install something?
Plus: When I went to the download page, I have these to download: Installer.exe MATLAB77.zip Communications_Toolbox42.zip Signal_Processing_Blockset68.zip Signal_Processing_Toolbox610.zip
I downloaded them all and installed. But when installing, it alerted me that no Simulink. How should I handle this?

I have the same problem.Here is my error.
An UndefinedFunction error was thrown on the workers for 'configurePin'. This might be because the file containing 'configurePin' is not accessible on the workers. Use addAttachedFiles(pool, files) to specify the required files to be attached. See the documentation for 'parallel.Pool/addAttachedFiles' for more details.
Caused by: Error using parallel_function>make_general_channel/channel_general (line 929) Undefined function 'configurePin' for input arguments of type 'double'.
I'm trying to communicate matlab and arduino.However, it's always running wrong.What's happened?

Error:Undefined function ‘execute’ for input arguments of type ‘double’.
raspberry pi simulink
Actually this can happened by many problems, one of them could be, the Simulink Support Package files didn’t downloaded correctly and may be there are missing file, and to be sure of that write:
for example which execute
and see what will be the result. If it returns the comment “Has no license available” or just gives error , then follow the below soution and if returns with path and a name of the file ,then restart your matlab and check ,if not solved it could be another problem.
Download all the package again, but before doing it, you have to remove SupportPackages folder in the following path: C:\Users\your_pc_ userrname\Downloads\MathWorks and start downloading the package ,it will works and mathworks will download the all the rquired files in that path for size not less that 716MB
i just restarted my pc and matlab and every thing works well ,thanks to these maklab team people http://www.maklabacademy.com/error-simulink-support-package-raspberry-pi-hardware-2016-2017/

In my case I was simply not in the correct working directory. Changed by either CD'ing into the correct directory, or using the UI to change working directory.

I got this message,
Undefined function 'kalman' for input arguments of type 'double'
I controlled all the licenses and the function is present in its controldesign folder How can I solve it?
Metin Ozturk 2018-7-31
It may be because the function you are trying to use is not available in your current MATLAB version. For example, if you use 'normalize' function in any version other than 2018, it will produce the same error, as the 'normalize' function was introduced in MATLAB 2018.

hi there~ i have an error like this one "Undefined function 'ziegler_nic' for input arguments of type 'double'." i've added some file to the path but it still won't work. it will be a big help for me if anybody can solve this case, thanks before
I have a matlab function which at a certain point calculates sin(2*pi*freq*t_array) (t_array in an array of size (1,2000).
I tried to call this function vi matlab.engine but I got the error message: "Undefined function 'sin' for input argument of type 'int64' "
I tried what is people suggested in this topic but it didn't work. I wanted to add the file 'sin.m' to my working directory but it is not a function script, it is a simple text.
I would be very grateful of any help
Thank you !

It sometimes gives you this error if you don't have the right toolboxes installed for the certain function.
If a particular function is causing an error. Try typing
If this results in like a certain toolbox is required for this function to work. Just click on the hyperlink or underlined link which is given in the terminal.
It will direct you to the appropriate package. Make sure you save any programs. Since installing the packages requires MATLAB to restart.
