`cdsrpv01`

computes
risky present value of a basis point (RPV01) for a credit default
swap (CDS) and conforms to the industry standards (ISDA CDS Standard
Model).

Compared with the previous version of Financial Instruments Toolbox™,
there are minor changes in the values computed by `cdsbootstrap`

, `cdsspread`

, `cdsprice`

,
and `cdsoptprice`

when
the starting dates do not fall on a payment date. The affected output
arguments are as follows:

`cdsbootstrap`

:`ProbData`

,`HazData`

`cdsspread`

:`Spread`

`cdsprice`

:`Price`

`cdsoptprice`

:`Payer`

,`Receiver`

While the magnitudes of the value changes are very small, they might affect users who depend on exact matches to previous values. These changes are caused by the modification of the way risky present value of a basis point (RPV01) is computed and these changes were made to better reflect the industry practice of paying CDS premiums only on specific payment dates.

`optimoptions`

support `optimoptions`

support
for `IRFitOptions`

For R2012b, error and warning message identifiers have changed in Financial Instruments Toolbox.

If you have scripts or functions that use message identifiers
that changed, you must update the code to use the new identifiers.
Typically, message identifiers are used to turn off specific warning
messages, or in code that uses a `try/catch`

statement
and performs an action based on a specific error identifier.

For example, because Fixed-Income Toolbox and Financial Derivatives Toolbox merged
to become Financial Instruments Toolbox, the `finfixed`

and `finderiv`

message
identifiers have changed to `fininst`

. If your code
checks for `finfixed`

or `finderiv`

message
identifiers, you must update it to check for `finisnt`

instead.

To determine the identifier for an error, run the following command just after you see the error:

exception = MException.last; MSGID = exception.identifier;

To determine the identifier for a warning, run the following command just after you see the warning:

[MSG,MSGID] = lastwarn;

`MSGID`

.
