Toolbox that contains wcommon?

I have a code to calculate tortuosity of 3D geometry. It contains one line below. [connect_voxels_index_match,slide_one_axis_index_match]= wcommon(connect_voxels_index,slide_one_axis_index);

However my MATLAB 2017a cannot find the definition of wcommon. Publisher said it is contained in a toolbox, but he does not remember. Anybody knows which toolbox has it? Or any same function as this?

Looking forward to your reply.

Hi Beak,

Did you find any same function as wcommon.m or a solution for this problem?

Thanks,

Ying

Hi!

There is a wcommon.m file available as a part of Wavelet Toolbox. (I used 'which -all' to fetch the path of the same)

>> which -all wcommon
C:\Program Files\MATLAB\R2018a\toolbox\wavelet\wavelet\wcommon.m

I looked up the function and found the below info as well:

%   WCOMMON Find common elements.
%   For two vectors X and Y with integer components,
%   [XI,YI] = WCOMMON(X,Y) returns two vectors
%   with 0 and 1 components such that:
%   XI(k) = 1 if X(k) belongs to Y otherwise XI(k) = 0 and 
%   YI(j) = 1 if Y(j) belongs to X otherwise YI(j) = 0.

Hope this helps!
