I have a cell array of strings with names of files that match certain criteria. Now want to test if each of these strings is 1) the name of a class and 2) if it is a class, is it a subclass of the MATLAB Unit T
is divisible by aa given number. I've gotten this script I have been working on: ifh=fopen(fname,'r');%open the file for reading [tk,ln]=strtok(ln); ifmod(tk/num==0) end fprintf(ofh,'%s ', tk); but I'm not sure how to get the test each to...
Check if a string is in a set of valid values. validStrings = ["wind","wonder","when"]; str = "wind"; validStr = validatestring(str,validStrings) validStr = "wind" Check if "WON" is in the set of valid values defined by validStrings. The string is a case-insensitive, partial...

s1=quad((r^2+r1^2)^0.5,0,x) 这一行 quad是数值积分函数，要求第一个参数为函数句柄，而不是符号变量，可以使用matlabFunction()将符号变量转为函数，参考修改后的代码：syms x r r1 r2 k s1 s xd yd u l x1 y1m=20;r=280/(1+(cos(x)/3));r1=diff(r,x,1);r2=r/r1;for...
