Why "Undefined function or variable 'wavedec3'. " when running a standalone application in Terminal?

I compiled a standalone application to extract radiomic features according to Create Standalone Application from MATLAB. After running the app in command line for seconds, errors popped up as "Undefined function or variable 'wavedec3'. " I figured out the reason was the app could not call the function "wavedec3" which comes from "Wavelet Toolbox".

Why "Wavelet Toolbox" was not included in MATLAB runtime as it is actually supported as stated in Support for MATLAB and Toolboxes ?

It is likely that you are running your compiled application on a machine without MATLAB Runtime: https://www.mathworks.com/products/compiler/matlab-runtime.html

Also note that the compiled applications are not cross-platform compatible (cannot go from Windows to Linux).

? If MCR were not present I would expect the executable to give up a lot earlier than that?

I finally fixed it. 'wavedec3' is a function from "Wavelet Toolbox", so go to "MATLAB > Apps > Get more apps > (search) Wavelet Toolbox > install". Afterwards, compile the APP over again.
