MATLAB: Matlab codegen and CLI/CLR class

matlab coderMATLAB Compiler

Hi everyone,

I'm trying to add some code generated from Matlab into a a project in C#. So basically the C# code will call a C++ CLI class that contains the code generated by Matlab. My question is how exactly do I have to do in order to make it work? I can see the big picture but not the fine prints of it( I'm very new to this). Is there any other way to do it?

Thanks in advance

Making a long story short. After generating the C shared library you add the project.H project.Lib and project.dll as a library and call it in your CLI class function. You would also have to initialize and terminate the function but after you figure it out doesn't seem to be that complicated.

MATLAB: Generate command-line command from library compiler project

You can use:

deploytool -build foo.prj

To build from the command line using the current settings in the project.

Form the os command line, you can use

deploytool /build foo.prj

These are current supported, but are on a path to deprecation. The command will be replaced with similar, but improved functionality in a future release.

MATLAB: Declaring variables for codegen

The basic requirement is that you need to specify three characteristics for each input argument of the entry-point functions:

The class of the variable (e.g. double, single, char, int32, etc.)
The array size (or at least the upper bound of each dimension)
The complexity of the variable (false indicates real-valued, true indicates complex).

In general, you do not need to specify these characteristics for any variables other than the input arguments of the entry-point functions, as long as MATLAB Coder can infer what they are from the code itself.

If you do not specify any of these characteristics for any of the input arguments, MATLAB Coder will assume the following default values:

the class will be double
the array size will be scalar (1 x 1)
the complexity will be false (real-valued)

The Coder GUI, however, will generally show <Undefined> for each input argument until you actually specify these three characteristics. If you do not specify any variable that is <Undefined>, then MATLAB Coder will return an error when you try to generate the code.

HTH.
