You can index into, reshape, and concatenate string arrays using standard array operations, and you can append text to them using the+operator. If a string array represents numbers, then you can convert it to a
String arrays store pieces of text and provide a set of functions for working with text as data. You can index into, reshape, and concatenate strings arrays just as you can with arrays of any other type. You also can access the characters in a string and append text to strings using ...
fmincon函数应用四种不同的算法:内点法(interior point);序列二次规划算法(SQP);有效集法(active set);信赖域有效算法(trust region reflective)。 如果采用SQP算法可以设置 OPTIONS = optimoptions('fmincon','Algorithm','sqp'),再把OPTIONS赋给fmincon
% INDEX is the sort order such that S = C(INDEX); % % Natural order sorting sorts strings containing digits in a way such that % the numerical value of the digits is taken into account. It is % especially useful for sorting file names containing index numbers with % different numbers ...
