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]

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.

I have all 'mw...' from native Smath 6179.

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.

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

And check if they are 32bit signed, output should look like this.
Code:
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 (100kb) downloaded 4 time(s).

I have personally tried, it does work.
