MATSLISE: Eigenvalues window: parameterized version    

Multiple values for one parameter


It is possible to define multiple values for one parameter in the specification of the problem to solve (e.g. 1:3:35 or [1,2,4,6]). This allows to compare several problems: e.g. to study how small changes in the boundary conditions or in the potential function, influence the problem.

Note: The directory predefined_problems contains some examples of the use of multiple parametervalues.

The Eigenvalues Window

The Calculate Eigenvalues-button

Pressing the Calculate Eigenvalues-button calculates the eigenvalues for each different value of the parameter. For each value of the parameter an entry (Run) is added in the Results-list.

The Select All-button

It is possible to select all the Runs by using the Select All-button. Specific Runs in the list can be selected by using the SHIFT- and CTRL-keys.

The Show data-button

The eigenvalues for a specific parameter-value can be consulted by selecting the corresponding Run and using the Show data-button.

The Plot-button

The eigenvalues are represented on a plot by selecting one or more Runs and choosing the Plot-button.

The Eigenfunctions-button

The eigenfunctions associated to the selected Runs are calculated by pressing the Eigenfunctions-button, which opens a new window (See The eigenfunctions: parameterized version)
