Specify String Scalar Inputs at the Command Line

You can define string scalar inputs at the command line. Programmatic specification of string scalar input types by using preconditioning (assert statements) is not supported.

To define string scalar inputs at the command line, use one of these procedures:

• Provide an Example String Scalar Input

• Provide a String Scalar Type

• Provide a Constant String Scalar Input

• Provide a Variable-Size String Scalar Input

Alternatively, if you have a test file that calls your entry-point function with example inputs, you can determine the input types by using coder.getArgTypes.

Provide an Example String Scalar Input

To provide an example string scalar to fiaccel, use the -args option:

fiaccel myFunction -args {"Hello, world"}

Provide a String Scalar Type

To provide a type for a string scalar to fiaccel:

1. Define a string scalar. For example:

   s = "mystring";

2. Create a type from s.

   t = coder.typeof(s);

3. Pass the type to fiaccel by using the -args option.

   fiaccel myFunction -args {t}

Provide a Constant String Scalar Input

To specify that a string scalar input is constant, use coder.Constant with the -args option:

fiaccel myFunction -args {coder.Constant("Hello, world")}

Provide a Variable-Size String Scalar Input

To specify that a string scalar input has a variable-size:

1. Define a string scalar. For example:

   s = "mystring";

2. Create a type from s.

   t = coder.typeof(s);

3. Assign the StringLength property of the type the upper bound of the string length and set VariableStringLength to true. For example, specify that type t is variable-size with an upper bound of 10.

   t.StringLength = 10;
   t.VariableStringLength = true;

   To specify that t is variable-size with no upper bound:

   t.StringLength = Inf;

   This automatically sets the VariableStringLength property to true.

4. Pass the type to fiaccel by using the -args option.

   fiaccel myFunction -args {t}
