How to resolve this issue in Cluster "Error using cluster Too many input arguments. Error in try_Clust (line 7) T = cluster(Z,'MaxClust',3);

I am getting error on my Mac Book OSx version

I just ran the live script ClusterDataUsingDistanceCriterionExample.mlx

I am pasting the code in short below (Its part of live script):

clear; clc;
load fisheriris
Z = linkage(meas,'average','chebychev');
T = cluster(Z,'MaxClust',3);
cutoff = median([Z(end-2,3) Z(end-1,3)]);
dendrogram(Z,'ColorThreshold',cutoff)

The error is as posted below:

Error using cluster

Too many input arguments.

Error in try_Clust (line 7)

T = cluster(Z,'MaxClust',3);

Details of the Matlab version being installed is here. For better assimilation I tried the same code on matlab.mathworks.com the online version. Error is the same.

Thanks in advance.

Hi,

I tried executing the said example at my end in MATLAB R2020b and it executed successfully without giving any errors. I suspect there is another function named "cluster" which is shadowing the MATLAB function "cluster". This is evident in the output of your "which cluster -all" command.

The cluster function which is being executed is :

/Users/makamkirankumar/Desktop/EMG_Analysis/emglab1.03/m files/cluster.m

Rather than the MATLAB defined function:

/Applications/MATLAB_R2020b.app/toolbox/stats/stats/cluster.m % Shadowed

It is recommended not to use the same function names as MATLAB defined functions. You can try renaming the user-defined "cluster" function to resolve the issue.

Thanks I got the error rectified.
