Can i know what is the solution for this error

Hello i found this error in matlab when i'm using kmeans function

Undefined function 'initkm' for input arguments of type 'single'.

Error in kmeans (line 65) center = initkm(cluster_n, data); % Initial cluster centers

[dpb]

Which release, which kmeans?

My version (R2012b) has no initkm in kmeans.m and line 65 is well within the header comment section, not even into executable code yet...

My version(R2012a) my OS is linux example: a=[1 3 4 5 6 3 2 9 6]; kmeans(a,3);

then i had the error

That runs just fine here...

Try

which kmeans

at command line -- sounds to me like you've got some other function in place of the one in the Statistics Toolbox. That much difference in m-file content doesn't sound right altho I guess there could have been extensive revisions between a and b releases. Unfortunately, I've no earlier version to compare to.

now i'm adding the function initkm i check it in the internet but i don't know the input

function [center, center_class] = initkm(cluster_n, data, data_class) % INITKM Find the initial centers for a K-means clustering algorithm.

Clearly you're not using the Matlab Statistics Toolbox kmeans

Whatever/wherever you obtained it is where to find support for it; the Matlab forum can't help in all likelihood.
