Adding a library path

Ronan — Sat, 05 Sep 2026 23:28:29 Z

I need to add a library path name to get an old style package .lib to run. Currently a have to manually add the path. How do I solve this?
Also should the package be convverted to .mla type? What is the difference?

Edit;- I am using windows 10

restart

download location https://github.com/fractal97/CLIFFORD

libname

(1)

I have to use the following to get the package to load

>	savelibname:="C:/Users/Ronan/Maple/toolbox/Cliffordlib"

(2)

>	libname:=savelibname,libname:

libname

(3)

>	with(eClifford)

(4)

This is a screen shot of what in in the library folder. It is a older type .lib package

This is what is in the .ini file

#savelibname:="C:\\Maple2020/Cliffordlib":
#libname:=savelibname,libname:
#savelibname:="C:\\Maple2020/Cliffordlib":
savelibname:="C:\\Users\Ronan\Maple\toolbox\Cliffordlib":
libname:=savelibname,libname:

filepathname:=cat(savelibname,"/","define.m"):
read filepathname:
filepathname:=cat(savelibname,"/","definemore.m"):
read filepathname:
read(cat(savelibname,"/","Walshpackage.m"));

GUI is unresponsive

Jean-Michel — Sat, 05 Sep 2026 18:46:28 Z

Hello,

Under Windows 11 Pro the GUI of Maple 2026.1 stuck Maple totally.

I can't even open a new document.

In Maple 2026.0 everything was ok...

This .1 release is unusable on my computer. I didn't dare to ask until today.

Open windows task manager I see that OpenJDK platform binary is the culprit.

Then.. I do NOT know what to do.

If someone has an idea I will be very happy.

Thanks and best,

Jean-Michel

Integrating the derivative of tanh

C_R — Thu, 03 Sep 2026 21:05:35 Z

I could not figure out why Maple does not return tanh. Instead a complex valued function for real arguments is returned. This is not recent. I tried down to Maple 2020. Is that correct?

>	D(tanh); plot(%)

>	int(D(tanh)(x),x);# I expected tanh plot(%);# ok, no plot for real valued x

Warning, unable to evaluate the function to numeric values in the region; complex values were detected

>	int(D(tanh)(x),x=0..infinity);# this result seems to be known in advance and fits to the above plot

(1)

>	int(D(tanh)(x),x=a..b); eval(%,[a=0,b=infinity]);# I expected 1 from (1) eval(%%,[a=0,b=50.]);# retruns complex for small values

Error, (in ln) numeric exception: division by zero

(2)

>	evalf(int(D(tanh)(x),x=0..50))

(3)

Let's try integrating the identical expression sech^2

(4)

>	is((sech^2=1-tanh^2)(x));# check identity

(5)

>	int(sech(x)^2,x);# what I expected

Numeric formatting ignored

Thomasbk — Thu, 03 Sep 2026 09:03:51 Z

Hi everyone,

I am experiencing what appears to be a problem with Numeric Formatting in Maple 2026.

I have a worksheet where I calculate a numerical value using evalf, for example:

evalf(1 - (3.7*90)/(10.4*3600))

which returns

0.4663461539

When I select the output and use the Context Panel → Numeric Format, for example:

Percent
2 decimal places

the preview in the math container changes accordingly (e.g. showing something like 0.45), but the actual numerical output below still displays as

0.4663461539

Changing the number format, decimal places, scientific notation, etc. seems to have no effect on the displayed output.

Even if not using evalf.

Is this the expected behavior in Maple 2026?

Does Numeric Formatting only apply to certain types of expressions or math containers?
Is there a known issue with formatting numerical output generated by evalf?
Am I missing a setting that enables formatting of worksheet output?

I have attached a screenshot illustrating the problem.

Any help or clarification would be appreciated.

Thanks!

Eliminating a discontinuity in an integrand?

Alfred_F — Wed, 02 Sep 2026 13:26:38 Z

I would like to calculate a definite integral in the attached file. Doing so numerically is straightforward. However, a symbolic approach initially fails due to three points of discontinuity in the integrand. Yet, these points can be remedied by taking limits. How can the domain in Maple be extended using these limits to achieve continuity across the entire domain?

dsolve series, number of terms?

Alfred_F — Mon, 31 Aug 2026 08:46:20 Z

I would like to solve a differential equation using a series expansion in the attached file for practice purposes. How can the number of terms in the series solution be adjusted? I couldn't find anything about this in the help text.
BTW:
The differential equation is exceptionally tricky for a symbolic solution ;-) .
