MATLAB: How to direct Matlab on which function to execute

Question

Hello,

Matlab has a PCA function, and I have implemented a PCA function.

In one script, I want to compare the results of Matlab's PCA versus mine. How can I do that?

I agree it is it not a wise idea to have conflict functions. A solution would be changing the name of my PCA, but I have many dependencies on my PCA so it is a hassle to change all the names.

Also, I can remove my PCA directory from the "path" in order to force matlab to use its function, but I don't see it as the correct way as well.

Is there a way to tell Matlab which PCA to use?

Thank you

Answer 1

At the command prompt, type

which -all pca

to see the full path to MATLAB's pca command and yours.

Reference the full path to the MATLAB function when you want to use it.
