Check If MATLAB Function Is Built-In Function Check whether theplotfunction is a built-in function or a file. A = exist('plot') A = 5 This indicates thatplotis a built-in MATLAB function. Input Arguments collapse all name—Name of variable, script, function, folder, or class ...

Objective function is returning undefined values at initial point. lsqcurvefit cannot continue. The error is in this sense self-explaining: You provide an initial guess to function 'lsqcurvefit', where the value of the objective function has undefined values. As a m...
Expressions that include relational operators on arrays, such asA > 0, are true only when every element in the result is nonzero. Test if any results are true using theanyfunction. limit = 0.75; A = rand(10,1) A =10×10.8147 0.9058 0.1270 0.9134 0.6324 0.0975 0.2785 0.5469 0.9575 0.9649...
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...
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 = ...
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 = ...
