Questions tagged [matlab-coder]

MATLAB Coder™ generates standalone C and C++ code from MATLAB® code. The generated source code is portable and readable.MATLAB Coder supports a subset of core MATLAB language features, including program control constructs, functions, and matrix operations. It can generate MEX functions that let you accelerate computationally intensive portions of MATLAB code and verify the behavior of the generated code.

How to use a switch construct with variable-length strings in Embedded Matlab?

I never liked Embedded MATLAB much, precisely because of situations like what I'm about to ask :) In my experience, conversion to Embedded MATLAB often takes a lot more effort than simply re-writing the thing in C (when you know C and the MATLAB API…

Variable named i386 generated by Matlab Coder

I'm generating code for a function with several variable-sized arrays. The code needs to be compiled in both linux (with gcc) and windows machines (with MinGW). To "ensure capacity" in those variables, Matlab creates several counter variables, named…

Matlab Coder throws mixed field type error in structure array while loading MAT file with coder.load

I'm working on a MATLAB Coder project where I want to load some constant values. After trying many possibilities, all unsuccessfully, I came up with the "coder.load" directive that loads variables from MAT files and assumes them as compile time…

Solving ODEs inside a Subsystem in Simulink

I'm trying to figure out how to solve a system of ODEs inside a subsystem in a Simulink model. Basically, each call to this subsystem, which happens at each tick of the simulation clock (fixed-step), entails solving the ODEs. So there's like a…

MATLAB Coder dynamically sized array of structs

I'm trying to use a dynamically growing array of structs in a piece of code that is supposed to be converted to C with Coder: I initialize the struct and then declare its fields variable size for coder, then i proceed to grow the struct. Note that i…

Matlab Coder force boolean_T to be native C99 bool type

How can I force matlab embedded coder to set "boolean_T" as "bool" C99 type? Without that, I need explicit cast conversion I/O signals mapping for int->boolean_t (not needed for int->bool).
