                                        SDVariable v)

Validate that the operation is being applied on a numerical SDVariable (not boolean or utf8). Some operations (such as sum, norm2, add(Number) etc don't make sense when applied to boolean/utf8 arrays

Parameters:

opName - Operation name to print in the exception

v - Variable to perform operation on

validateNumerical

protected static void validateNumerical(String opName,
                                        String inputName,
                                        SDVariable v)

Validate that the operation is being applied on a numerical SDVariable (not boolean or utf8). Some operations (such as sum, norm2, add(Number) etc don't make sense when applied to boolean/utf8 arrays

Parameters:

opName - Operation name to print in the exception

v - Variable to validate datatype for (input to operation)

validateNumerical

protected static void validateNumerical(String opName,
                                        String inputName,
