The following table shows LabVIEW data types and the corresponding data types in the MATLAB® software. (MathScript RT Module) This table also shows the corresponding LabVIEW MathScript data types. You can change the data type of an input or output terminal on a script node.

LabVIEW Data Type MATLAB® Script Node Data Type MathScript Node Data Type

Double-precision, floating-point numeric
Real Scalar»DBL

Complex double-precision, floating-point numeric
Complex Scalar»CDB

1D array of double-precision, floating-point numeric
1-D Array of Real 1D-Array»DBL 1D

1D array of complex double-precision, floating-point numeric

(MathScript RT Module) You can use additional data types with the MathScript Node, including the state-space, transfer function, and zero-pole-gain models of the LabVIEW Control Design and Simulation Module. You must have the Control Design and Simulation Module installed to use these models. Refer to the Control Design and Simulation Module documentation for more information about these models.

Note Note  MathScript represents strings internally as arrays of the corresponding ASCII character codes.

The MATLAB script node and the MathScript Node handle 1D array inputs only by row. To change the orientation of a 1D array from row to column or column to row, transpose the array before you perform operations on elements of the array.

Use the Conversion VIs and functions or the Path/Array/String Conversion functions to convert a LabVIEW data type to a data type that the MathScript RT Module or the MATLAB software supports.
