From within your MATLAB ® code, you can directly call external C/C++ code, also called custom code or legacy code. To call C/C++ functions, use coder.ceval. The code generator integrates your C/C++ code into the C/C++ code generated from MATLAB.
codegen options function-args {func_inputs} generates C or C++ code from a MATLAB function with inputs of type func_inputs and builds the generated code. Use the options argument to specify settings such as the code generation configuration object.
Functions and Objects Supported for C/C++ Code Generation. You can generate efficient C/C++ code for a subset of MATLAB ® built-in functions and toolbox functions and System objects that you call from MATLAB code. These functions and System objects are listed in the following tables.
Use coder.ceval to call the C standard library function cosh() from the generated code. Create a MATLAB function callCosh that takes an input of type double, representing an angle in radians, and calculates the hyperbolic cosine of that angle using the C function cosh().
Generate C/C++ Code from a MATLAB Function. This example shows the recommended workflow for generating C/C++ code from a MATLAB® function. The steps in this workflow are: Prepare MATLAB code for code generation. Generate and test MEX function. Generate and inspect C/C++ code.
2 lis 2015 · outdata[r+height*c+height*width] =output[r][c]; You don't need height*width as the offset. r + height*c is enough to access a single channel 2D matrix in column-major order.
MATLAB Coder lets you generate C code from your MATLAB code. You can generate stand-alone ANSI-C code or C code that includes the necessary interfaces to run within MATLAB as compiled MEX file. This quick start guide focuses on how to generate stand-alone ANSI-C code. Refer to ^Preparing MATLAB Code for MATLAB Coder: a Quick Start Guide _ [1] for
