Conversion of Java Types to MATLAB Types

Pass Data from Java to MATLAB Production Server

When you pass data as input arguments to deployed MATLAB^® functions from Java^®, MATLAB Production Server™ converts the data into equivalent MATLAB data types.

Value Passed to Java Method	Input type Received by MATLAB	Dimension of Data in MATLAB
`java.lang.Byte`, `byte`	`int8`	{1,1}
`byte[]` `data`	`int8`	{1, `data.length`}
`java.lang.Shortshort`	`int16`	{1,1}
`short[]` `data`	`int16`	{1, `data.length`}
`java.lang.Integer`, `int`	`int32`	{1,1}
`int[]` `data`	`int32`	{1, `data.length`}
`java.lang.Long`, `long`	`int64`	{1,1}
`long[]` `data`	`int64`	{1, `data.length`}
`java.lang.Float`,`float`	`single`	{1,1}
`float[]` `data`	`single`	{1, `data.length`}
`java.lang.Double`, `double`	`double`	{1,1}
`double[]` `data`	`double`	{1, `data.length`}
`java.lang.Boolean`, `boolean`	`logical`	{1,1}
`boolean[]` `data`	`logical`	{1, `data.length`}
`java.lang.Character`, `char`	`char`	{1,1}
`char[]` `data`		{1, `data.length`}
`java.lang.String` `data`		{1, `data.length`()}
`java.lang.String[]` `data`	`cell`	{1, `data.length`}
`java.lang.Object[]` `data`	`cell`	{1, `data.length`}
`T[]` `data`	MATLAB type for `T`	{ `data.length`, `dimensions`(`T`[`0`]) }, if `T` is an array
`T[]` `data`	MATLAB type for `T`	{ 1, `data.length`}, if `T` is not an array

Pass Data from MATLAB Production Server to Java

When deployed MATLAB functions return output arguments, MATLAB Production Server converts the data into equivalent Java data types.
