laplace(..) with 1D display #3104

Closed rtoy closed 1 week ago

In both console and xmaxima mode with display2d:false I get

laplace('diff(a(t), t), t, s ); ---> s * ?%laplace(a(t), t, s ) - a(0)

instead of the expected

s * 'laplace(a(t), t, s ) - a(0)

Using ilt(..) doesn't cure this display behavior, but desolve(..) does cure this behavior (for some mysterious reason).

This is a minor complaint, since I can simply avoid the problem with 2D display, or else start my session with:

(%i1) ( display2d:false, desolve('diff(a(t), t) = - b*a(t), a(t ) ) )$ (%i2) laplace('diff(a(t), t), t, s); (%o2) s * 'laplace(a(t), t, s ) - a(0)

NOUN and VERB properties for the functions laplace and ilt are added in rev. 1.10.

The linear display now works as expected. Closing this bug report as fixed.
