Using bndyield function results in discrepancies with Excel and other calculation sources?

Greetings,

bndyield is a funcion that calculates the yield to maturity for a fixed-income security. Let's take an IBM bond as an example. The CUSIP '459200JG7' refers to a (almost 10 year to maturity from today) IBM corporate bond with the following characteristics:

Coupon: 3.45% Maturity: 02/19/2026 Day Count: 30/360 Coupon Frequency: Semi-Annual No Odd Coupons (Last or First)

Let's say that I'm purchasing this bond today for a settlement Date (t+3) of May 10th, 2016. Let's say that I am purchasing this Bond at a price of $106.8125 and assuming a redemption (par) amount of $100, I would like to know what is the yield of maturity I am getting.

If I use the bndyield formula in MATLAB:

Yield = bndyield(106.8125,0.0345,'05/10/2016','02/19/2026','Period',2,'Basis',1)

I get a result of 0.026530631026615 or 2.6531% yield (rounded up)

Using an Excel formula of YIELD...

=YIELD("5/10/2016","02/19/2026",0.0345,106.8125,100,2,0)

...and using the same inputs, I get the following result:

0.0265385150 or a yield of 2.6539%.

Please note that the value of 1 for Basis in MATLAB pertains to 30/360 SIA, which is the 30/360 US (NASD) convention. Please note that the value of 0 for Basis in Excel pertains to 30/360 US (NASD) convention.

Furthermore, when I utilize Bloomberg as a tool to calculate the yield given the parameters for this particular bond...

=BDP("459200JG7 Corp","yld_cnv_bid","px_bid=106.8125","settle_dt=20160510")

I get a result of 2.65385150, which translates to a yield of 2.6539%, the same value obtained through the usage of the excel formula.

Perhaps I'm missing some additional Parameter in MATLAB or is there a calculation discrepancy that is taking place?

Please advice on this matter. Thanks in advance!
