Just wondering how I do a loop over the contents of the table. I need both the index variable and the stored value associated with it.

This one apparently doesn't work.

F_vRk := table()

table( [ ] )

(1)

F_vRk["a"] := 1

1

(2)

F_vRk["b"] := 2

2

(3)

"for ind, val in F_vRk  do print(ind,val)  end do"

1, F_vRk

(4)

NULL

Maple apparently has managed to destroy the last working piece of code in the Units package in the 2022 release.

This code is working in Maple 2021, but not in 2022 anymore.

with(Units[Simple])

alpha := 45*Unit('degree')

45*Units:-Unit(arcdeg)

(2)

NULL

if alpha = 0 then

Error, cannot determine if this expression is true or false: 0 < 1/4*Pi

evalf(sin(alpha))

Is it possible to read and/or convert Mapleflow sheets to Maple?

Any idea why I can't write Excel output to my standard Documents directory?

Writeout to a different directory outside seems to work.

Any specific Windows rights that need to be given to a directory for writeout?

There seems to be a bug in Maple 2021, latest release. Not sure if this was in previous versions.

When checking off the "Show Column Header" in Datatables, the cells are becoming invisible, while the column header still remains.

Show Row Header on the other side works fine.
