MATSLISE: Potential plot window

The Potential plot window

The Potential plot window for the Mathieu problem.

The Potential plot window for the Mathieu problem (with parameter r).

Potential function field

This field shows the expression of the potential function. For a Sturm-Liouville problem this field contains the potential function of the associated Schrödinger problem V(r), where r is the Sturm-Liouville unknown variable.

X/Y Limits-fields

X:The lower and upper limit of the interval over which the potential function is evaluated and plotted. For a Sturm-Liouville problem these fields represent the lower and upper limit of the x-interval of the associated Schrödinger problem.

Y:axis limits for the Y-axis.

Points-field

The number of points used to plot the potential function. When this plotted potential function had no smooth form, the number of points should be increased.

Plot-button

When this button is clicked, the part of the potential function between a and b is calculated (and displayed), i.e. evaluated in n points, where n is equal to the value entered in the Points-field.
