Pass .NET Data Types to MATLAB Functions

When you pass .NET data as input arguments to MATLAB^® functions, the engine converts the data into equivalent MATLAB data types.

These tables show how the engine maps .NET data types to MATLAB data types.

.NET Data Type (Scalar)	Resulting MATLAB Type (Scalar)
`System.Double`	`double`
`System.Single`	`single`
`System.SByte`	`int8`
`System.Byte`	`uint8`
`System.Int16`	`int16`
`System.UInt16`	`uint16`
`System.Int32`	`int32`
`System.UInt32`	`uint32`
`System.Int64`	`int64`
`System.UInt64`	`uint64`
`System.Boolean`	`logical`
`Numerics.Complex`	complex `double` MATLAB does not support complex numbers for other numeric types.
`MathWorks.MATLAB.Types.MATLABStruct`	`struct`

.NET Data Type (1-D Vector)	Resulting MATLAB Type (1-D Vector)
`System.Double[]`	`double`
`System.Single[]`	`single`
`System.SByte[]`	`int8`
`System.Byte[]`	`uint8`
`System.Int16[]`	`int16`
`System.UInt16[]`	`uint16`
`System.Int32[]`	`int32`
`System.UInt32[]`	`uint32`
`System.Int64[]`	`int64`
`System.UInt64[]`	`uint64`
`System.Boolean[]`	`logical`
`Numerics.Complex[]`	complex `double` MATLAB does not support complex numbers for other numeric types.
`MathWorks.MATLAB.Types.MATLABStruct[]`	`struct[]`

.NET Data Type (N-D Array)	Resulting MATLAB Type (N-D Array)
`System.Double[,,...]`	`double`
`System.Single[,,...]`	`single`
`System.SByte[,,...]`	`int8`
`System.Byte[,,...]`	`uint8`
`System.Int16[,,...]`	`int16`
`System.UInt16[,,...]`	`uint16`
`System.Int32[,,...]`	`int32`
`System.UInt32[,,...]`	`uint32`
`System.Int64[,,...]`	`int64`
`System.UInt64[,,...]`	`uint64`
`System.Boolean[,,...]`	`logical`
`Numerics.Complex[,,...]`	complex `double` MATLAB does not support complex numbers for other numeric types.
`MathWorks.MATLAB.Types.MATLABStruct[,,...]`	`struct[,,...]`

Constants	Resulting MATLAB Value
`System.Double.NaN`	Result of `NaN("double")`
`System.Single.NaN`	Result of `NaN("single")`
`System.Double.PositiveInfinity`	Result of `Inf("double")`
`System.Single.PositiveInfinity`	Result of `Inf("single")`
`System.Double.NegativeInfinity`	Result of `-Inf("double")`
`System.Single.NegativeInfinity`	Result of `-Inf("single")`

Note

The .NET System.Decimal type is not supported for scalar, vector, or array arguments.

.NET Data Type (Scalar)	Resulting MATLAB Type (Scalar)
`System.String`	`string`
`System.Char`	`char`
null `System.String`	`<missing>` value in `string`

.NET Data Type (1-D Vector)	Resulting MATLAB Type (1-D Vector)
`System.String[]`	`string`
`System.Char[]`	`char`

.NET Data Type (N-D Array)	Resulting MATLAB Type (N-D Array)
`System.String[,,...]`	`string`
`System.Char[,,...]`	`char`

.NET Data Type	Resulting MATLAB Type
