Hi. You can't build matrices A and B that way, but you can with stack and augment. BTW, it seems that the interval where it finds the solution is the [0,1] giving overflow error for 1000 steps and the interval [0,5]

Best regards.
Alvaro.

The mwode* functions are part of the plugin Matlab Runtime Library; it ask you to install when you open a worksheet that contains these functions or you can download manually from the extensions manager.

If you like my plugins please consider to support the program buying a license; for personal contributions to me: paypal.me/dcprojects

I have the plugin of Matlab runtime library and it has no ode solvers of matlab

I have all 'mw...' from native Smath 6179.
that was installed from the option installer
rather than from plugins.
Does it suggest to re-install your version ?

It may not work on windows 64-bit or linux/mono systems.
There is a trick for windows however.

I did everything written in that link but I still can't find those matlab functions

Did you also made Solver.exe 32bit?
When uni wrote that information, SMath was not splitted to Solver and Writer.
Run these two commands as administrator.

CorFlags.exe /32bit+ Solver.exe
CorFlags.exe /32bit+ SMathStudio_Desktop.exe

And check if they are 32bit signed, output should look like this.

C:\Program Files (x86)\SMath Studio> CorFlags.exe Solver.exe
Microsoft (R) .NET Framework CorFlags Conversion Tool.  Version  4.8.9037.0
Copyright (c) Microsoft Corporation.  All rights reserved.

Version   : v2.0.50727
CLR Header: 2.5
PE        : PE32
CorFlags  : 0x3
ILONLY    : 1
32BITREQ  : 1
32BITPREF : 0
Signed    : 0

If method above doesn't work, use this new version of CorFlags. CorFlags.zip (99 KiB) downloaded 21 time(s).

I have personally tried, it does work.
