A while ago I have written a FEX submission that extends the capabilities of find to also work for 3D and up: findND (e.g. a syntax like [x,y,z,val]=findND(A)). I would like to be able to shadow the built-in function, so I have the option of simply using [x,y,z,val]=find(A) in my code. My function would then use the code from this previous question to get a handle to the built-in function, so my function catches the call to find and does its thing if it needs to. Based on this question, I would have thought that it would be relatively easy to do this: just ignore the warning.
However, when I try this, it doesn't work: Matlab still calls the built-in function. list = which('find', '-all') shows my function as the first entry (for R2017b and R2012b).
It makes sense that Matlab would use the built-in, as that is the function precedence order, but in that case I don't understand why which would think that the local function would take precedence.
Is there a way to do this (preferably without requiring the end-user to jump through many hoops), or should I give up and just use my function under its own name?
