suppose a simple matlab function
//add.m
function result=add(left ,right)
result=left + right;
//end of add.m
use matlab comtool to encapsulate the function in fun.dll
and then use it in c#.net
i create a c# web service project to call
the matlab function add
but the function declaration has changed:
//create a instance;
fun.funClass st=new fun.funClass();
when i want to write st.add(paramete rs)
the declaration is
void add(int nargout,ref object,object,o bject)
which in matlab there're only two (left and right)
Could anyone please tell what's the meaning of int nargout and ref object?
And how to call the function add correctly? 2 5315
Hi,
my guess is
nargout is number of output arguments
ref object will hold the result
the two 'val' objects are the input parameters
So I would be looking for C# code something like
object myResult;
int num1 =5;
int num2 =6;
st.add(1,myResu lt,num1,num2)
ie the following c# is similar in intent
private void button1_Click(o bject sender, EventArgs e)
{
int x = 5;
int y = 6;
object myResult;
myResult = new object();
Addem(ref myResult,x,y);
int z;
if( int.TryParse(my Result.ToString (),out z))
MessageBox.Show (" Result is " + z.ToString());
}
private void Addem(ref object myResult, int x, int y)
{
myResult = x + y;
}

I've spent the past day or so working through the various complexities in
calling Matlab routines from Python (please do not reply with suggestions to

how to access it through COM).
Matlab's COM API is actually pretty clean/simple, but there are a few
wrinkles, some undocumented "magic strings", and some odd surprises. Also,
the Matlab COM API was designed for...

Hi;
Does anyone know if we can call matlab for a python or bash script while
feeding the matlab script some command line arguments? I have an
interactive matlab script which i want to automate by feeding the args
from a script.
I know this is probably more suitable to a matlab group but any ideas will
be appreciated.

I am desperately looking for a way to call Python from Matlab. I have become
used to Python's rich syntax and large number of libraries, and feel
ridiculously clumsy being stuck with Matlab's rather restricted facilities
for doing other things than standard mathematical work.
Does anyone know of good techniques (or readily available software) for
achieving a cross-language support between Python and Matlab?

Do any body know how to use the functions available in the MATLAB
using C#?
( To be specific, functions COHERE used to find Coherence and TFE to
calculate Transfer function are needed. These functions are available
in the MATLAB SP toolbox)
These functions require input waveforms X and Y, which is nothing but
two array of samples (datatype=double).

Dear all,
Can C++/STL/Boost do the vectorized calculation as those in Matlab?
For example, in the following code, what I really want to do is to

All other parameters such as t, l1, l2, l3, etc. are scalars...
But u is a vector.

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
