Statup script executes as a function

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.

Hi,

I have tried reproducing this on MATLAB 2020a on windows. I did not get any error.

I have created a file named startup.m in the path given by userpath command. And added this script to it. I did not get any error message or sound. Can you tell me which MATLAB version you are using?

Hello Prudhvi, thanks for your help.

My version of MatLab is 2020b. It used to work fine on my previous computer.

I check my userpath folder. The script is in a folder within the userpath folder. But I guess this is not where the issue comes from.

Anthony.

@Anthony Amorosi: please show the complete output of this command:

which startup -all

Hi, here it is

C:\Users\antho\Documents\MATLAB\StartupDir\startup.m

[Stephen23]

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.
