MATLAB API for COM Automation Server

GetWorkspaceData

Data from Automation server workspace

Synopsis

IDL Method Signature

HRESULT GetWorkspaceData([in] BSTR varname, [in] BSTR workspace, 

    [out] VARIANT* pdata)      

Microsoft Visual Basic Client

GetWorkspaceData(varname As String, workspace As String) As Object      

MATLAB Client

D = GetWorkspaceData(h,'varname','

workspace

')

Description

D = GetWorkspaceData(h,'varname','

workspace

')

 gets data stored in variable 

varname

 from the specified 

workspace

 of the server attached to handle 

h

 and returns it in output argument 

D

. The values for 

workspace

 are 

base

 or 

global

.

Use 

GetWorkspaceData

 instead of 

GetFullMatrix

 and 

GetCharArray

 to get numeric and character array data, respectively. Do not use 

GetWorkspaceData

 on sparse arrays, structures, or function handles.

For VBScript clients, use the 

GetWorkspaceData

 and 

PutWorkspaceData

 functions to pass numeric data to and from the MATLAB® workspace. These functions use the 

variant

 data type instead of the 

safearray

 data type used by 

GetFullMatrix

and 

PutFullMatrix

. VBScript does not support 

safearray

.

GetFullMatrix

Matrix from Automation server workspace

Synopsis

IDL Method Signature

GetFullMatrix([in] BSTR varname, [in] BSTR workspace, 

    [in, out] SAFEARRAY(double) *pr, [in, out] SAFEARRAY(double) *pi)      

Microsoft Visual Basic Client

GetFullMatrix(varname As String, workspace As String, 

    [out] XReal As Double, [out] XImag As Double      

MATLAB Client

[xreal ximag] = GetFullMatrix(h,'varname','

workspace

',zreal,zimag)

Description

[xreal ximag] = GetFullMatrix(h,'varname','

workspace

',zreal,zimag)

 gets matrix stored in variable 

varname

 from the specified 

workspace

 of the server attached to handle 

h

. The function returns the real part in 

xreal

 and the imaginary part in 

ximag

. The values for 

workspace

 are 

base

 or 

global

.

The 

zreal

 and 

zimag

 arguments are matrices of the same size as the real and imaginary matrices (

xreal

 and 

ximag

) returned from the server. The 

zreal

 and 

zimag

 matrices are commonly set to zero.

Use 

GetFullMatrix

 for 2D matrices with values of type 

double

 only. Use 

GetVariable

 or 

GetWorkspaceData

 for other types. To use higher dimensional matrices, reshape the 2D matrix after receiving it from MATLAB®.

For VBScript clients, use the 

GetWorkspaceData

 and 

PutWorkspaceData

 functions to pass numeric data to and from the MATLAB workspace. These functions use the 

variant

 data type instead of the 

safearray

 data type used by 

GetFullMatrix

 and 

PutFullMatrix

. VBScript does not support 

safearray

.
