Default , where is the total propagation time
Energy step to output from Fourier transform. Sampling rate for the Fourier transform. If you supply a number equal or smaller than zero, then the sampling rate will be $2 \pi / T$, where $T$ is the total propagation time.
Input filename. The original filename which is going to be converted in the format specified in OutputFormat. It is going to convert various files, it should only contain the beginning of the name. For instance, in the case of the restart files, it should be one space ' ‘.
Uses Fast Fourier Transform as implemented in the external library.
Uses polinomial approach to the computation of discrete Fourier Transform.
It uses the same variable described in how to obtain spectrum from
a time-propagation calculation.
The format of the mesh function will be convert from the binary file.obf.
The format of the output function is set by OutputHow variable.
A fourier transform of the mesh function will be computed.
It requieres that ConvertStart and ConvertEnd have to be set.
Convert utility will generate a new mesh function constructed by linear
combination of scalar function of different mesh functions,
This variable is used to generate a new mesh function as a linear combination different mesh function having the same mesh. Each row defines an operation for for a single mesh function. The format of the block is the following:
‘variable name’ | ‘folder’ | ‘file’ | ‘operation’
