MATSLISE: Distorted Coulomb problems    

The Construct-button

When the Construct-button is clicked the partition for the Schrödinger problem is generated and a second window (Eigenvalues-window) is opened where the user starts the eigenvalue-calculations.

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).

The partition is 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 (unless xmax was set to inf: in this case a good truncated integration interval is determined during the eigenvalue-computation).

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 ( l*(l+1)/x^2 + S(x)/x + R(x)): The potential plot window.

The Exit-button

The whole MATSLISE-application is closed when the Exit-button is pressed.
