I am getting the following error when I try running dfield9 in MATLAB 2020b

Error using feval
Unrecognized function or variable 'dftp3066'.

Error in dfield9 (line 1600)
Ww = feval(dfcn,Tt',Xx');

Error in dfield9 (line 1523)
dfield9('dirfield',dfdisp);

Error while evaluating UIControl Callback.

Any help on resolving this issue? Thanks!

Responding to Teodo's error, the following fix appears to work in MATLAB R2020a

addpath(tmpdir)

Could you please update this function to work when being called from the Live Editor?

When I call the function from a Live Script in R2019b, I encounter the following error:

Error using uimenu
First argument must be a valid parent, such as a Figure or Panel object.
Error in dfield9 (line 625)
meload = uimenu(mefile,'label','Load an equation ...',...

Could you reproduce this error on your machine and help me resolve the issue?

Thanks!

Could You please fix it for R2019a, it reports this error for the default equation:

"Error using feval
Undefined function or variable 'dftp2531'.

Error in dfield9 (line 1598)
Ww = feval(dfcn,Tt',Xx');

Error in dfield9 (line 1521)
dfield9('dirfield',dfdisp);

Error while evaluating UIControl Callback."

Thank You.
