nag_file_line_read (x04bb) is used by NAG Library functions to read formatted records from an external file. All formatted input from an external file by NAG Library functions is performed by calls to nag_file_line_read (x04bb).
Compulsory Input Parameters
nin – int64int32nag_int scalar
The Fortran unit number which identifies the file to be read from. If nin < 0 (not a valid Fortran unit number), then no input occurs.
reclen – int64int32nag_int scalar
The maximum length of the record in characters.
Optional Input Parameters
Input Parameters Omitted from the MATLAB Interface
recin – string
The first LEN(recin) characters of the record read from unit nin, padded with trailing blanks if the record was shorter than LEN(recin).
