In this node, one can enter an analytic expression in the content field to define the wave function $\psi$.
An annotated screenshot of the node is shown below.
The node has the following inputs:
In the node, any analytic expression can be written in the content field. The wavefunction can be used either directly, or it can be numerically normalized by checking the ''Normalize output" checkbox which normalizes the output.
After all the inputs are provided, the node gives the following output:
An example is shown below where a gaussian function is defined with its inputs and the normalized output is shown in the plot.
