These are questions asked by tomleslie

While debugging something unrelated to Maple, I noticed in Windows task manager that the process

C:\Program Files\Maple 2016\jre\bin

had a Memory(Private Working Set) of 2,251,088K - roughly 10x the memory footprint of any other running process.

Is this normal?

Not a real issue for me (machine has 16G ram) - but it just *looks* wrong

In case it matters I'm running Maple 2016.1 on Win7, 64bit

It seems as if arrays can only be displayed in 2-D form when the array dimensions start at 1.

Sometimes I want to construct arrays where an index starts from 0 (or other values). This is purely for my convenience in some problems. However such arrays do not display in 2-D form. Consider the displayed form of

Array(1..4,1..5,(i,j)->i+j);

Array(1..4,0..4,(i,j)->i+j);

Why doesn't the latter 'display' in 2-D form?

For the last 24hrs or so I have found it almost impossible to upload worksheet files in response to questions.

My usual approach is

Big green up-arrow:
(uploader pop-up appears)

Browse files

(this still works)

Upload file

This is the problem step - I generally just get "waiting for Mapleprimes" in my browser's annunciator box: and I wait, and wait, (as in >5 minutes) and still this step does not complete. Just to be annoying, every once in a while the file will upload as normal, such but success is now the exception

I'm seeing the same issue in Firefox 45.0.2 and Chrome 50.0.2661.75mon Win 7, 64-bit.

Anyone else seeing the same issue?

 

 

The font size in the output pane of the standard interface, interactive debugger is really, really small and I can't figure out how to increase it. (Other than drop my screen resolution from its native 2560x1440, which makes it bigger but "fuzzier" - not a huge improvement for tired eyes!!)

Consider the equation

eqn1:=5^(2*abs(y-1)+2) = (1/15625)*625^abs(y-1);

and note that

eval( eqn1, y=-3);
eval( eqn1, y=5);

both return valid solutions. So why does

testeq(eqn1);

throw a numeric exception.

Given the manual description of testeq(), I would expect it to return either true or FAIL - but not a numeric exceprion!!!!

Any ideas?
