The Construct-button
When the Construct-button is clicked the partition is
calculated and a second window (Eigenvalues-window) is opened where the user is able to obtain the eigenvalues
of the problem he specified. When the user entered several values for a parameter (e.g. 1:5
),
then for each value a separated problem is constructed and in
further stages the user can solve each of this problems and
compare the solutions (See Eigenvalues window: parameterized version).
This makes it possible to study the behaviour of the solution when the parameter changes.
Calculating the partition means that the step sizes are chosen and the terms of the propagation matrix are calculated for each interval.
E
, once the partition has been fixed. For a regular problem, the partition is thus generated only once
and it is never modified further on: this means that in the Eigenvalues-window several sets of eigenvalues of the same problem
can be calculated one after the other, without recalculating the partition.
The Stop-button
A click on the Stop-button interrupts the calculations.
The Plot Potential-button
The Plot potential-button generates a plot of the potential function V(x)
in
the interval [a,b]
: The potential plot window. When a vector of values for a parameter was entered, then
for each parameter-value, a potential function is plotted.
The Exit-button
The whole MATSLISE-application is closed when the Exit-button is pressed.
