How do I access individual elements of a matrix returned by a MATLAB COM object to Visual Basic?
显示 更早的评论
I have a MATLAB COM Builder generated object and I am trying to access the values of a returned matrix in Visual Basic.
For example:
Dim load As Variant
Call MatlabObject.myFunct(2, load, score, msparseX, 1#)
The MATLAB function declaration is
[load, score] = myFunct(X,numEle)
If I attempt to acess the individual values of "load" with the Array property I receive the error
"Let procedure not defined"
This puzzles me because I can access the individual values of the input array msparseX.Array(1) without any difficulty.

The msparseX works because it is a MWSparse object and has the Array property defined for accessing the nonzero array values of the sparse array. However, since the "load" variable is simply a VARIANT array, you have to index into it directly as in:
Call oMatlabObject.myFunct(2, load, score, msparseX, 1#)
load(1,1)
