length函数是求最大数组维度的长度。 语法 代码语言:javascript 代码运行次数:0 运行 AI代码解释 L=length(X) 输入数组,指定为标量、向量、矩阵或多维数组。支持复数。 提示 要计算字符串或字符向量中的字符数量,可以使用strlength函数。 length不对表执行运算。要检查表的维度,可以使用height、width或size函数。 说...

An alternative procedure is to press the “Select from array” button in the “Objects” group. After pressing this button, a list of numeric matrices is presented. In this list, select the “idx_validation” array that was saved before. This will ensure that the same indices are used for...

作为理工科的社畜,懂计算会计算是一个必不可少的技能,其中尤其是对于土木工程人来说,结构力学、弹塑性力学、计算力学是数值计算中无法逾越的一道坎。由于Matlab简单使用,好学好操作,工科人往往都喜欢使用Matlab来实现数值算法。但是Matlab有几个缺点:
constr = true; end % Process objective function if ~isempty(FUN) % will detect empty string, empty matrix, empty cell array % constrflag in optimfcnchk set to false because we're checking the objective, not constraint funfcn = optimfcnchk(FUN,'fmincon',length(varargin),funValCheck,flags....
