| - | There are two methods that can be used to connect to a DPG from MATLAB. The second, newer method is more robust and can access all the features of a DPG. | + | |

| * MATLAB always sends its data as a 2D array (matrix). Even if you only have one column of data, you will still need to use the "2D" download vector commands. | * MATLAB always sends its data as a 2D array (matrix).

| * The "Int" integer format referenced in the [[Programming Reference]] is the same as the MATLAB data type int32. The "Double" data type is the same as MATLAB's type double. Most matrices in MATLAB are type double, unless specifically cast to a different data type. | * The "Int" integer format referenced in the [[Programming Reference]] is the same as the MATLAB data type int32.

| * Be aware of any vector length restrictions for the particular pattern generator you are communicating to. For example, the length of a vector on the DPG2 must be divisible by 256. | * Be aware of any vector length restrictions for the particular pattern generator you are communicating to.

| * The Interleaved commands take one vector and split it between the two output ports on the pattern generator. For single ports DACs which take interleaved data, you will need to interleave the channels before providing the data to the pattern generator. | * The Interleaved commands take one vector and split it between the two output ports on the pattern generator.

It is advisable to select the index of the //hardwarePlugins// array by querying the //FriendlyName// and selecting the one that has the correct name. | + | <WRAP round help>The index of //hardwarePlugins// corresponding to a particular hardware type could change if you ever update your DAC Software Suite.
