• Variable-sized inputs are only supported when the SumMode property of the governing fimath is set to Specify precision or Keep LSB.

• For variable-sized signals, you may see different results between the Embedded MATLAB subset and MATLAB.

  • In the Embedded MATLAB subset, the output for variable-sized signals is always computed using the SumMode property of the governing fimath.

  • In MATLAB, the output for variable-sized signals is computed using the SumMode property of the governing fimath when both inputs are non-scalar. However, if either input is a scalar, MATLAB computes the output using the ProductMode of the governing fimath.

convergent

ctranspose

diag

• If supplied, the index, k, must be a real and scalar integer value that is not a fi object.

disp

divide

• Any non-fi input must be constant; that is, its value must be known at compile time so that it can be cast to a fi object.

• Complex and imaginary divisors are not supported.

double

end

eps

• Supported for scalar fixed-point signals only.

• Supported for scalar, vector, and matrix, fi single and fi double signals.

eq

• Not supported for fixed-point signals with different biases.

fi

• Use to create a fixed-point constant or variable in the Embedded MATLAB language subset.

• The default constructor syntax without any input arguments is not supported.

• The syntax fi('PropertyName',PropertyValue...) is not supported. To use property name/property value pairs, you must first specify the value v of the fi object as in fi(v,'PropertyName',PropertyValue...).

• Works for all input values when complete numerictype information of the fi object is provided.

• Works only for constant input values (value of input must be known at compile time) when complete numerictype information of the fi object is not specified.

• numerictype object information must be available for nonfixed-point Simulink inputs.

fimath

• Fixed-point signals coming in to an Embedded MATLAB Function block from Simulink are assigned the fimath object defined in the Embedded MATLAB Function block dialog in the Model Explorer.

• Use to create fimath objects in Embedded MATLAB code.

• Any non-fi input must be constant; that is, its value must be known at compile time so that it can be cast to a fi object.

mpy

• When you provide complex inputs to the mpy function inside of an Embedded MATLAB Function block, you must declare the input as complex before running the simulation. To do so, go to the Ports and data manager and set the Complexity parameter for all known complex inputs to On.

• numberofelements and numel both work the same as MATLAB numel for fi objects in the Embedded MATLAB language subset.

numerictype

• Fixed-point signals coming in to an Embedded MATLAB Function block from Simulink are assigned a numerictype object that is populated with the signal's data type and scaling information.

• Returns the data type when the input is a nonfixed-point signal.

• Use to create numerictype objects in Embedded MATLAB code.
