double fake_drand48 (  ) 

drand48 ************************************************************* Cheap replacement for drand48 which is not available on the PC.

FLOAT32* ReadNFloats ( FILE *  File,
uinT16  N,
FLOAT32  Buffer[] 
)

ReadNFloats ************************************************************* Parameters: File open text file to read floats from N number of floats to read Buffer pointer to buffer to place floats into Globals: None Operation: This routine reads N floats from the specified text file and places them into Buffer. If Buffer is NULL, a buffer is created and passed back to the caller. If EOF is encountered before any floats can be read, NULL is returned. Return: Pointer to buffer holding floats or NULL if EOF Exceptions: ILLEGALFLOAT History: 6/6/89, DSJ, Created.

PARAM_DESC* ReadParamDesc ( FILE *  File,
uinT16  N 
)

ReadParamDesc ************************************************************* Parameters: File open text file to read N parameter descriptions from N number of parameter descriptions to read Globals: None Operation: This routine reads textual descriptions of sets of parameters which describe the characteristics of feature dimensions. Return: Pointer to an array of parameter descriptors. Exceptions: ILLEGALCIRCULARSPEC ILLEGALESSENTIALSPEC ILLEGALMINMAXSPEC History: 6/6/89, DSJ, Created.

PROTOSTYLE ReadProtoStyle ( FILE *  File  ) 
PROTOTYPE* ReadPrototype ( FILE *  File,
uinT16  N 
)

ReadPrototype ************************************************************* Parameters: File open text file to read prototype from N number of dimensions used in prototype Globals: None Operation: This routine reads a textual description of a prototype from the specified file. Return: List of prototypes Exceptions: ILLEGALSIGNIFICANCESPEC ILLEGALSAMPLECOUNT ILLEGALMEANSPEC ILLEGALVARIANCESPEC ILLEGALDISTRIBUTION History: 6/6/89, DSJ, Created.

uinT16 ReadSampleSize ( FILE *  File  ) 

ReadSampleSize *********************************************************** Parameters: File open text file to read sample size from Globals: None Operation: This routine reads a single integer from the specified file and checks to ensure that it is between 0 and MAXSAMPLESIZE. Return: Sample size Exceptions: ILLEGALSAMPLESIZE illegal format or range History: 6/6/89, DSJ, Created.

FLOAT32 UniformRandomNumber ( FLOAT32  MMin,
FLOAT32  MMax 
)

UniformRandomNumber ******************************************************** Parameters: MMin lower range of uniform distribution MMax upper range of uniform distribution Globals: None Operation: This routine computes a random number which comes from a uniform distribution over the range from MMin to MMax. Return: Uniform random number Exceptions: None History: 6/6/89, DSJ, Created.

void WriteNFloats ( FILE *  File,
uinT16  N,
FLOAT32  Array[] 
)

WriteNFloats *********************************************************** Parameters: File open text file to write N floats to N number of floats to write Array array of floats to write Globals: None Operation: This routine writes a text representation of N floats from an array to a file. All of the floats are placed on one line. Return: None Exceptions: None History: 6/6/89, DSJ, Created.

void WriteParamDesc ( FILE *  File,
uinT16  N,
PARAM_DESC  ParamDesc[] 
)

WriteParamDesc ************************************************************ Parameters: File open text file to write param descriptors to N number of param descriptors to write ParamDesc array of param descriptors to write Globals: None Operation: This routine writes an array of dimension descriptors to the specified text file. Return: None Exceptions: None History: 6/6/89, DSJ, Created.

void WriteProtoList ( FILE *  File,
uinT16  N,
PARAM_DESC  ParamDesc[],
LIST  ProtoList,
BOOL8  WriteSigProtos,
BOOL8  WriteInsigProtos 
)
void WriteProtoStyle ( FILE *  File,
PROTOSTYLE  ProtoStyle 
)

WriteProtoSyle ********************************************************** Parameters: File open text file to write prototype style to ProtoStyle prototype style to write Globals: None Operation: This routine writes to the specified text file a word which represents the ProtoStyle. It does not append a carriage return to the end. Return: None Exceptions: None History: 6/8/89, DSJ, Created.

void WritePrototype ( FILE *  File,
uinT16  N,
PROTOTYPE Proto 
)

WritePrototype ************************************************************ Parameters: File open text file to write prototype to N number of dimensions in feature space Proto prototype to write out Globals: None Operation: This routine writes a textual description of a prototype to the specified text file. Return: None Exceptions: None History: 6/12/89, DSJ, Created.
