Istalled once, with this problem. Uninstalled this and previous 2024 versions. Re-istalled. Same problem. Unistalled. Tried to install version 2024b from internet. Download problem. Copied 2024b from Laptop over partially istalled version on Tower. Works fine, as below.

Answer 1

[Star Strider]

From the documentation --

Can I use MATLAB Home on 2 computers simultaneously?

• The MATLAB Home License can only be used on a single computer at a time.

That may be the problem.

I suggest that you Contact Support if this is not the problem you are experiencing.

.

[ODE]

Actually you can license the home version on two computers, but no more.

[Walter Roberson]

@ODE that is not in accorandance with the license agreement.

dbtype(fullfile(matlabroot,'license_agreement.txt'), '686:689')

686       (ii) A Named User may install the Programs on up to four (4) different
687       Computers but may not use a Program on more than two (2) Computers
688       simultaneously, except that Student and Home Licenses are limited to a
689       single Computer. 

Answer 2

[Walter Roberson]

The most common cause of problems such as these, is if the system with the problem has installed a third-party .m file with the same name as one used by MATLAB, so the third-party file is being called instead of the normal .m file.

It looks to me as if most likely the problem would have to do with a file named "seconds.m" . Try

which -all seconds

The typical output would look similar to

/Applications/MATLAB_R2025a.app/toolbox/matlab/datatypes/duration/seconds.m

seconds is a built-in method % gpuArray method

/Applications/MATLAB_R2025a.app/toolbox/parallel/array/distributed/@distributed/distributed.m % distributed method

/Applications/MATLAB_R2025a.app/toolbox/matlab/bigdata/@tall/seconds.m % tall method

/Applications/MATLAB_R2025a.app/toolbox/parallel/array/distributed/@codistributed/seconds.m % codistributed method

Answer 3

[ODE]

SOLUTION:

After copying 2025a to my Tower from my Laptop, it executed correctly and "figure" worked without a problem. Then I realized I had not set up my "setup.m" in the local toolbox. After I did the problem re-appered. So the problem was in my start up file. The beginning is shown below. Turned out the "figure" command caused the problem in 2025a, but not 2024b. This was a legacy command from long ago for a signal processing toolbox I created for myself. No longer needed and it was commented out. Now 2025a works for the figure command.

%STARTUPSAV   Startup file
%   Change the name of this file to STARTUP.M. The file 
%   is executed when MATLAB starts up, if it exists 
%   anywhere on the path.  In this example, the
%   MAT-file generated during quitting using FINISHSAV
%   is loaded into MATLAB during startup.
