How can I price a FORWARD floating rate note by the FLOATBYZERO function in the Financial Instruments Toolbox?

Hi,

My issue is to price a FORWARD floating rate note. The optional argument 'StartDate' is not accepted by this function but I can see that it is accepted in the floatbyzero function used in the swapbyzero function !

Hereunder is a portion of my code (StartDate is signaled as invalid) :

[Price,DirtyPrice,OutputCashFlows,CFlowDates] = floatbyzero(...
    RateSpec, Spread, 'Settle', Maturity, ...
    'Reset', FloatReset, 'Principal', Principal, 'ProjectionCurve', ProjRateSpec...
    'StartDate', StartDate )

Hereunder is a copy paste of a portion of swapbyzero function source code (StartDate is validated by matlab) :

% --------------------------------------------------------------
% Find prices for each one of the instruments
% --------------------------------------------------------------
[FloatFullPrice, FloatPrice,FloatCF,FloatCFDates] = floatbyzero(FloatRateSpec, Spreads, Settle,...
    Maturity, 'Reset',FloatResets, 'Basis',FloatBasis, 'Principal',Principal,...
    'EndMonthRule',EOM,'LatestFloatingRate',LatestFloatingRate,...
    'AdjustCashFlowsBasis',AdjustCashFlowsBasis,'Holidays',Holidays,...
    'BusinessDayConvention',BusinessDayConvention,'ForwardRateSpec',ForwardRateSpec, ...
    'StartDate', StartDate);

Could somebody help me please ?

Thanks in advance,

Clement.
