| DeterminantString(//NF//,//Inds1//,//Inds2//,...) creates a string of length //NF// and sets all characters to '0', except for those indices included in //Inds1// etc, which it sets to '1'. This automatizes the input of functions like //[[documentation:language_reference:functions:NewWavefunction|NewWavefunction()]]// or //[[documentation:language_reference:functions:Eigensystem|Eigensystem()]]//. | DeterminantString(//NF//,//Inds1//) creates a string of length //NF// and sets all characters to '0', except for those indices included in //Inds1// etc, which it sets to '1'.
