Hi there,

I defined a startup.m script to excute when I start MatLab. I followed all of the instructions in Specify Startup Options.

When I start MatLAb, I get the following error lines

Attempt to execute SCRIPT startup as a function:
C:\Users\antho\Documents\MATLAB\StartupDir\startup.m

Hopefully the startup script does work properly! But it is very anoying to have that "error sound" and message that appears everytime I run MatLab ...

Here is my startup.m file

set(groot, ...
    'defaultAxesFontSize',14, ...
    'defaultAxesLabelFontSize',1.35, ...
    'defaultTextFontSize',14, ...
    'defaultTextFontSizeMode','manual',...
    'defaultLegendFontSize',18, ...
    'defaultLegendFontSizeMode','manual',...
...
    'defaultTextInterpreter','latex',...
    'defaultAxesTickLabelInterpreter','latex',...
    'defaultLegendInterpreter','latex',...
...
    'defaultLineLineWidth',2, ...
...
    'defaultAxesXGrid','on', ...
    'defaultAxesYGrid','on', ...
    'defaultLegendBox','on', ...
    'defaultLegendLocation', 'northeast',...
    'defaultAxesBox', 'on' ...
    )
%% Check
disp('statup.m all done!');

It isn't a function, and it should not be one!

Do anyone knows how to fix this ?

Thanks!

Anthony.

Interesting. Try the following:

rename the file (e.g. add an X to the name)
rehash the toolbox cache https://www.mathworks.com/help/matlab/ref/rehash.html
restart MATLAB
try creating an empty startup script.
restart MATLAB

Do you have any third-party toolboxes installed?

Hi Stephen,

I tried your suggestions but it was not helping.

But when I renamed the startup file, I remember I should also be changing the text in the Target field of my MatLab shortcut icon, as it was specified in Specify Startup Options.

"C:\Program Files\MATLAB\R2020b\bin\matlab.exe" -r "startup"

At first it did not solve the issue. But then I had the idea of simply removing -r "startup" and I got my problem fixed!!

Maybe this MatLab documentatin in Specify Startup Options is not up-to-date, or I maybe I got it wrong, but in any case the target field should have been left as it is by default.

Thanks anyway @Stephen Cobeldick and @Prudhvi Peddagoni for helping me with this anoying issue.
