Hello

I have a .mat file named DATA.mat that contains some data and an anonymous function 'standardizeFun':

DATA.mat contains the following

Z1 = 1x8479 cell

Z2 = 1x8479 cell

standardizeFun

standardizeFun =
function_handle with value:
@(x)(x-mean(cell2mat(Z1),2))./mean(cell2mat(Z2),2)

when I load DATA.mat i get the following error:

load('DATA.mat')
Warning: Could not find appropriate function on path loading function handle H:\old_directory\stdz.m>@(x)(x-mean(cell2mat(Z1),2))./mean(cell2mat(Z2),2) 

However, the standardizeFun function works completely fine despite the error.

I have no idea why it is referencing H:\old_directory\stdz.m - this was an old directory that should have no relationship to the current project and I don't see any place where this string should even be attached to the DATA.mat file

I thought that perhaps something was attached to the standardizeFun structure, but doesnt look that that directoryfile shows up there either

>> f = functions(standardizeFun)
struct with fields:
function: '@(x)(x-mean(cell2mat(Z1),2))./mean(cell2mat(Z2),2)'
type: 'anonymous'
file: ''
workspace: {[1×1 struct]}
within_file_path: ''
f.workspace{1}
ans = 
  struct with fields:
    Z1: {1×8479 cell}
    Z2: {1×8479 cell}

Can someone please explain why this error is showing up and what I can do to fix it (or if I need to do anything since it seems to be working fine despite the error?)

thanks!
