The run-time output of an extrinsic function is anmxArray, also known as a MATLAB array. The only valid operations formxArraysare: Storing anmxArrayin a variable. Passing anmxArrayto an extrinsic function. Returning anmxArrayfrom a function back to MATLAB. ...
S-functions or system functions provide a powerful mechanism for extending the capabilities of the Simulink®environment. AnS-functionis a computer language description of a Simulink block written in MATLAB®, C, C++, or Fortran®. S-functions use a special calling syntax called the S-functio...
(cnt)=myQuad(-2,x); b(cnt),c(cnt); end plot(a,b,'r',a,c,'b') \end{lstlisting} \section{Experiment Theory and Results} Given function f(x), and its range of x [a,b], it is possible to estimate its integral in range [a,b] by quandratic interpolation based on “Simpson...
问题在于，自定义函数f时，软件并没有把x0,y0值换成相应的数值，还是定义成字符串。像这种问题，还不如直接在窗口下执行快。>>x0=0.5,y0=10 >>R=1;L=20;l=L/2;>>b=R^2+x0^2-2*x0*R*sin(x);>>eq=sin(x)*(1/(b+(y0-l)^2)^0.5-1/(b+(y0+l)^2)^0.5)eq = ...
如果用quad来计算数值解，需要知道D R r 的具体值，例如：>> r=3; R=2; D=4;>> df=@(x)(r.^2*acos((r-(D-(R-sqrt(R.^2-x.^2)))./r)-(r-(D-(R-sqrt(R.^2-x.^2))).*sqrt(r.^2-(r-(D-(R-sqrt(R.^2-x.^2))).^2));>> Q=quad(df,0,2)Q = ...
2000SV.COF should all be zipped into an archive with the name EMM_Secular_Variations.zip and placed into ./Magnetism/data . If all of the data for a single year is loaded, then a .mat file containing the data is placed in the data folder to speed up subsequent calls to the function...
