getTflArgFromString

Create code replacement argument based on specified name and built-in data type

Syntax

arg = getTflArgFromString(hTable,name,datatype)

Description

arg = getTflArgFromString(hTable,name,datatype) creates a code replacement argument that is based on a specified name and built-in or fixed-point data type.

The IOType property of the created argument defaults to 'RTW_IO_INPUT', indicating an input argument. For an output argument, change the IOType value to 'RTW_IO_OUTPUT' by directly assigning the argument property.

This function does not support matrices. To create a matrix argument, use the argument class RTW.TflArgMatrix as shown in Small Matrix Operation to Processor Code Replacement, Matrix Multiplication Operation to MathWorks BLAS Code Replacement, and Matrix Multiplication Operation to ANSI/ISO C BLAS Code Replacement.

Examples

Create and Add an Output Argument

This example shows how to use getTflArgFromString to create an int16 output argument named y1. Then, the example adds the argument as a conceptual argument for a code replacement table entry.

hLib = RTW.TflTable;
op_entry = RTW.TflCOperationEntry;
.
.
.
arg = hLib.getTflArgFromString('y1', 'int16');
arg.IOType = 'RTW_IO_OUTPUT';
op_entry.addConceptualArg(arg);

Input Arguments

hTable — Handle to a code replacement table

handle

The hTable is a handle to a code replacement table previously returned by hTable = RTW.TflTable.

Example: hLib

name — Specifies the name to use for a code replacement argument

character vector | string scalar

Example: 'y1'

datatype — Specifies a built-in data type or a fixed-point data type to use for the code replacement argument

'integer' | 'int8' | 'int16' | 'int32' | 'long' | 'long_long' | 'uinteger' | 'uint8' | 'uint16' | 'uint32' | 'ulong' | 'ulong_long' | 'single' | 'double' | 'boolean' | 'logical' | 'void'

Built-in data type or fixed-point data type to use for the code replacement argument. You can specify fixed-point data types using the fixdt function from Fixed-Point Designer™ software; for example, 'fixdt(1,16,2)'. To specify a pointer argument, use the symbol * after the data type name; for example, 'double*'.

Example: 'integer'

Example: 'double*'

Output Arguments

arg — Handle to the created code replacement argument

handle

The arg is a handle to the created code replacement argument, which can be specified to the addConceptualArg function.
