使用引用调用(call-by-reference)的一个原因是可以对参数进行完美转发。它有自己的规则 template<typename T> void passR(T&& arg) { } std::string s = "hi"; passR(s); // OK: T deduced as std::string& (also the type of arg) passR(std::string("hi")); // OK: T deduced as std:...
The filter order N and frequency array F must be specified. If the frequency grid GF and weights W are unspecified, the function determines those values automatically. Get function [dh,dw] = fresp(N,F,GF,W) W = [1;1]*(W(:).'); W = W(:); type = 'lowpass'; mags = ...
Also you can define extra flags to pass to specific projects:BINUTILS_NATIVE_FLAGS_EXTRA, BINUTILS_TARGET_FLAGS_EXTRA, GCC_EXTRA_CONFIGURE_FLAGS, GDB_NATIVE_FLAGS_EXTRA, GDB_TARGET_FLAGS_EXTRA, GLIBC_TARGET_FLAGS_EXTRA, NEWLIB_TARGET_FLAGS_EXTRA. Example:GCC_EXTRA_CONFIGURE_FLAGS=--with-gmp=/...

Simulink can pass N-D array data to custom code functions in C Caller blocks, and receive data from such blocks. When you do so, you must specify the correct array layout to achieve the intended results. See Default function array layout and Exception by function. For examples of the use...
