ISubSet = instdelete(InstSet,Name,Value)
deletes instruments are from ISubSet if all the name-value
pairs Field, Index, and
Type conditions are met. An instrument meets an individual
Field condition if the stored data matches any of the rows
listed in the Data.
Retrieve the instrument set variable ExampleInst from the data file InstSetExamples.mat. The variable contains three types of instruments: Option, Futures, and TBill.

InstSet — Instrument variable for collection of instruments structure
Instrument variable for a collection of instruments, specified as an
instrument set structure. Instruments are classified by type; each type can
have different data fields. The stored data field is a row vector or
character vector for each instrument. For more information on the
InstSet variable, see instget.
Data Types: struct
Name-Value Pair Arguments
Specify optional
comma-separated pairs of Name,Value arguments. Name is
the argument name and Value is the corresponding value.
Name must appear inside quotes. You can specify several name and value
pair arguments in any order as
Name1,Value1,...,NameN,ValueN.
Number of fields, specified as the comma-separated pair consisting of
'FieldName' and an
NFIELDS-by-1 cell array of
character vectors listing the name of each data field to match with data
values.
Data Types: char | cell
'Data' — Number of values vector
Number of values, specified as the comma-separated pair consisting of
'Data' and a
NVALUES-by-M array or
NFIELDS-by-1 cell array of
acceptable data values for each field. Each row lists a data row value
to search for in the corresponding FieldName. The
number of columns is arbitrary and matching ignores trailing
NaNs or spaces.
Data Types: char | cell
'Index' — Number of instruments vector
Number of instruments, specified as the comma-separated pair
consisting of 'Index' and a
NINST-by-1 vector restricting
positions of instruments to check for matches. The default is all
indices available in the instrument variable.
Data Types: char | cell
'Type' — Number of types vector
Number of types, specified as the comma-separated pair consisting of
'Type' and a
NTYPES-by-1 cell array of
character vectors restricting instruments to match one of types. The
default is all types in the instrument variable.
ISubSet — Updated variable containing a collection of instruments structure
Updated variable containing a collection of instruments, returned as an
instrument set structure. ISubSet contains instruments
not matching the input criteria. Instruments are
deleted from ISubSet if all the
Field, Index, and
Type conditions are met. An instrument meets an
individual Field condition if the stored data matches
any of the rows listed in the Data. See instfind for more
examples on matching criteria.
