PCA function suddenly Stop working with error
显示 更早的评论
Hi everyone,
I'm using PCA to reduce the dimensions of my data and it was working without any problems, then when I came the next day and ran the MATLAB the PCA started throwing errors. I tried the exact example from MATLAB documentation (including using the same data in the example) but same error. below is my code followed by the error:
load hald
coeff = pca(ingredients)
the error:
Error using pcaklm (line 73)
Unknown type specified
Error in pca (line 53)
[w,truefrac] = pcaklm(mfilename,varargin{:});
------------------------------------------------------------------------------------------------------
My MATLAB version is R2021b
My OS is Ubuntu LTS 20.04

The line
[w,truefrac] = pcaklm(mfilename,varargin{:});
Try calling
which pca -all
from the command line to see what functions are in your path.
An internet search on pcaklm suggests that you might inadvertently be calling the ECGdeli Toolbox version. Perhaps you installed that?

I think the easiest solution for you is to use pathtool to move the Stats toolbox version of pca to be higher priority than the ECGdeli version.
