Hello!

I need to write the C code for a function I have in Matlab and I thought about using the Matlab Coder. The function basically performs a numeric integration, but there are huge arrays of struct as inputs. I'll be using only C so I need to declare and define these arrays of structs in C.

Does Matlab have a tool to do that?

Thank you!

Hey Marcelo,

I understand that you want to know that if there is a way to allocate an array of structs from a .MAT to C

However, you will need to manually declare and define the arrays of structs in C. MATLAB Coder provides a way to specify the data types of the inputs and outputs of the generated C code, but it does not generate C code for the data itself. You will need to write the C code to create and populate the arrays of structs based on the input data from your application.

MATLAB Coder has some limitations when generating C code from MATLAB code. Some of these limitations include:

Not all MATLAB functions can be converted to C code. For example, functions that use dynamic memory allocation or recursion cannot be converted.
Some MATLAB language features are not supported in C code, such as variable-length argument lists and nested functions.
The generated C code may not be as efficient as hand-written C code, especially for complex algorithms.

I hope this helps!
