问题 Currently I am trying to call MATLAB directly in Visual Studio, but it seems not working. To be clear, take the following demo case as an example, i.e. use MATLAB to compute 2+3 . It is expected that the result, i.e. ans = 5 , should be printed in line printf("%s\n", buf); , which turns out to be empty. By the way, the MATLAB engine is opened ( engOpen() ) successfully. #include <stdio.h> #include <thread> #include "engine.h" Engine *matlab; void thread_func() { // set printing buffer char

Are there C like pre-processor directives for Octave and Scilab to be used for intercompatible code?

阅读更多关于 Are there C like pre-processor directives for Octave and Scilab to be used for intercompatible code?

问题 In C / C++ languages one can use macros or as called "per-processor directives" to instruct the compiler how the code should be read. The simple commands of #def , #ifdef , #ifndef , #else , #endif ... give the compiler the ability to check for Operating system, compiler and other environment information. I know Octave and Scilab are interpreted languages, but I'm wondering if is there any way to tell the interpreter to replaces parts of script while loading it? For example can I write a code
